步骤

第 1 步：Select Historical Period and Color Palette

Choose a period and identify its characteristic color language. Color in ornament is never arbitrary — each period has a palette rooted in available pigments, cultural symbolism, and material context.

Historical Ornament Periods with Characteristic Palettes:
┌───────────────────┬─────────────────┬────────────────────────────────────────────────────────┐
│ Period            │ Date Range      │ Characteristic Palette                                  │
├───────────────────┼─────────────────┼────────────────────────────────────────────────────────┤
│ Egyptian          │ 3100–332 BCE    │ Lapis blue, gold/ochre, terracotta red, black, white   │
│                   │                 │ Mineral pigments: flat, unmodulated, high contrast      │
├───────────────────┼─────────────────┼────────────────────────────────────────────────────────┤

├───────────────────┼─────────────────┼────────────────────────────────────────────────────────┤
│ Byzantine         │ 330–1453 CE     │ Gold (dominant), deep blue, crimson, purple, white      │

├───────────────────┼─────────────────┼────────────────────────────────────────────────────────┤
│ Islamic           │ 7th–17th c.     │ Turquoise/cobalt blue, white, gold, emerald green       │
│                   │                 │ Tile glazes: luminous, saturated, geometric precision    │
├───────────────────┼─────────────────┼────────────────────────────────────────────────────────┤
│ Romanesque        │ 1000–1200 CE    │ Ochre, rust red, deep green, dark blue, cream           │
│                   │                 │ Manuscript and stone: earthy, muted, mineral-derived     │
├───────────────────┼─────────────────┼────────────────────────────────────────────────────────┤
│ Gothic            │ 1150–1500 CE    │ Ultramarine blue, ruby red, emerald green, gold, white  │
│                   │                 │ Stained glass + illumination: saturated, luminous        │
├───────────────────┼─────────────────┼────────────────────────────────────────────────────────┤
│ Renaissance       │ 1400–1600 CE    │ Rich earth tones, azure blue, gold leaf, warm greens    │
│                   │                 │ Oil and fresco: naturalistic, modulated, subtle          │
├───────────────────┼─────────────────┼────────────────────────────────────────────────────────┤
│ Baroque/Rococo    │ 1600–1780 CE    │ Pastel pink, powder blue, cream, gold, soft green       │

│                   │                 │ teal. Organic, muted, nature-derived palette             │
└───────────────────┴─────────────────┴────────────────────────────────────────────────────────┘

If the user specified a period, confirm and note its characteristic palette
If "surprise me," select randomly — weight toward periods with rich color traditions (Islamic, Byzantine, Gothic, Art Nouveau)
Note the material context (fresco, mosaic, tile, stained glass, print) as this affects how color renders

预期结果： A clearly identified period with its characteristic palette and material context understood.

失败处理： If the user requests a period not in the table, research its color language using WebSearch for "[period] ornament color palette pigments" and construct an equivalent entry. Historical pigment availability is a reliable guide to period-authentic color.

第 2 步：Define Color Palette

Translate the historical palette into a specific 3-5 color set with defined roles.

Color Role Framework:

Color Distribution (60/30/10 Rule):
┌──────────────┬────────────┬──────────────────────────────────────────┐
│ Role         │ Proportion │ Function                                  │
├──────────────┼────────────┼──────────────────────────────────────────┤
│ Dominant     │ ~60%       │ Ground color or primary structural color  │
│ Secondary    │ ~30%       │ Motif fill or supporting structural color │
│ Accent       │ ~10%       │ Highlights, details, focal points         │
│ (Optional)   │ —          │ Additional accent or metallic (gold)      │
│ (Optional)   │ —          │ Background / ground if different from     │
│              │            │ dominant                                   │
└──────────────┴────────────┴──────────────────────────────────────────┘

Color Harmony Approaches:

Period-Authentic: Use only colors available to the historical period's pigments and materials
Complementary: Opposing colors on the color wheel (e.g., blue and gold/orange) — high contrast
Analogous: Adjacent colors (e.g., sage green, teal, muted blue) — harmonious, subtle
Triadic: Three equally spaced colors (e.g., red, blue, gold) — vibrant, balanced

Select 3-5 colors with named roles (dominant, secondary, accent, optional)
Choose the harmony approach
Assign approximate hex values or descriptive color names
Note the color mood: muted/antique, balanced/natural, or vivid/saturated

Example Palette Definitions:

Islamic Tilework: turquoise (dominant), white (secondary), cobalt blue (accent), gold (detail) — analogous + metallic — vivid
Art Nouveau Poster: sage green (dominant), dusty rose (secondary), amber gold (accent) — analogous — muted
Byzantine Mosaic: gold (dominant), deep blue (secondary), crimson (accent), white (detail) — complementary — vivid

预期结果： A palette of 3-5 named colors with roles, proportions, harmony approach, and mood defined.

失败处理： If color selection feels arbitrary, anchor to the period's material context. Ask: "What pigments were physically available?" and "What was the ground material?" (gold leaf on vellum, glaze on ceramic, paint on plaster). The material constrains and authenticates the palette.

第 3 步：Analyze Motif Structure

Understand the structural grammar of the chosen motif, extending the monochrome analysis with color-to-structure mapping.

Perform the same structural analysis as
```
ornament-style-mono
```
Step 2:
- Symmetry type (bilateral, radial, translational, point)
- Geometric scaffold (circle, rectangle, triangle, band)
- Fill pattern (solid, line-filled, open, mixed)
- Edge treatment (clean, organic, interlocking)
Add color-to-structure mapping:
- Which structural elements receive which colors?
- Does color follow form (each shape gets one color) or flow (color gradients cross structural boundaries)?
- Where does the accent color appear? (Typically at focal points, intersections, or small detail elements)
- What color is the ground/background?

Example Mapping:

Islamic Star Pattern:
- Star forms: turquoise (dominant)
- Interlocking geometric ground: white (secondary)
- Star center details: cobalt blue (accent)
- Outline/border: gold (detail)
→ Color follows form strictly — each geometric shape is one flat color

预期结果： A structural description with explicit color assignments for each structural element.

失败处理： If the color-to-structure mapping is unclear, study historical examples using WebSearch for "[period] [motif] ornament color" and observe how color was actually used. Historical ornament almost always uses color to clarify structure, not obscure it.

第 4 步：Construct Color Prompt

Build the text prompt for Z-Image generation, incorporating color palette and rendering style.

Prompt Template:

[Rendering style] of [motif name] ornament in the [period] style,
[composition type], [color palette description],
[color mood], [structural details from Step 3],
[application context], [additional qualifiers]

Color-Appropriate Rendering Styles:

```
painted ornament
```
— brushwork visible, opaque colors, fresco or oil quality
```
illuminated manuscript
```
— gold leaf, rich jewel tones, vellum ground
```
glazed ceramic tile
```
— glossy surface, flat color, precise edges
```
stained glass
```
— translucent color, dark leading lines between shapes
```
watercolor illustration
```
— transparent washes, soft edges, paper visible
```
enamel on metal
```
— hard glossy color, metallic ground
```
mosaic
```
— small tesserae, visible gaps between pieces, luminous
```
printed poster
```
— flat color areas, Art Nouveau or Arts & Crafts quality

Color Description in Prompts:

Name specific colors: "turquoise blue and gold on white ground"
Describe the mood: "muted antique tones" or "vivid saturated jewel colors"
Specify distribution: "blue dominant with gold accents" or "warm earth tones with red details"

Example Prompts:

glazed ceramic tile ornament in the Islamic style, geometric star pattern, turquoise blue and white with cobalt blue accents and gold outlines, vivid saturated colors, repeating tessellation, Iznik tilework quality

illuminated manuscript border in the Gothic style, vine and trefoil ornament, ultramarine blue and ruby red with gold leaf details on cream vellum, rich jewel tones, vertical panel, medieval book of hours quality

watercolor illustration of Art Nouveau floral ornament, whiplash curves with lily motif, sage green and dusty rose with amber gold accents, muted organic tones, vertical panel, Alphonse Mucha influence

预期结果： A prompt of 25-50 words that specifies rendering style, motif, period, composition, and explicit color information.

失败处理： If the prompt produces color that does not match the palette, front-load the color description in the prompt (put it before the motif description). Z-Image weights earlier prompt tokens more heavily. Also try naming specific hex colors or well-known pigment names (ultramarine, vermillion, ochre).

第 5 步：Configure Generation Parameters

Select resolution and generation parameters. Color ornament often benefits from slightly more inference steps than monochrome.

Resolution by Application (same as ornament-style-mono):
┌────────────────────┬─────────────────────┬────────────────────────────────┐
│ Application        │ Recommended         │ Rationale                      │
├────────────────────┼─────────────────────┼────────────────────────────────┤
│ Medallion / Roundel│ 1024x1024 (1:1)     │ Radial symmetry needs square   │
│ Tile / Repeat Unit │ 1024x1024 (1:1)     │ Square for seamless tiling     │
│ Horizontal Frieze  │ 1280x720 (16:9)     │ Wide format for running border │
│ Vertical Panel     │ 720x1280 (9:16)     │ Portrait format for columns    │
│ Wide Border        │ 1344x576 (21:9)     │ Ultrawide for architectural    │
│ General / Flexible │ 1152x896 (9:7)      │ Balanced landscape format      │
│ Large Detail       │ 1536x1536 (1:1)     │ Higher res for fine color work │
└────────────────────┴─────────────────────┴────────────────────────────────┘

Select resolution based on application context
Set
```
steps
```
to 10-12 for color work (color detail and palette accuracy benefit from more steps)
Set
```
shift
```
to 3 (default)
Choose
```
random_seed: true
```
for exploration or
```
random_seed: false
```
with a specific seed for reproducibility
Record all parameters for documentation

预期结果： A complete parameter set. Note that color ornament generally needs 10+ steps for good palette fidelity.

失败处理： If unsure, use 1024x1024 at 10 steps. This is a reliable default for most color ornament contexts.

第 6 步：Generate Image

Invoke the Z-Image MCP tool to produce the ornament.

Call
```
mcp__hf-mcp-server__gr1_z_image_turbo_generate
```
with:
- ```
prompt
```
  : the constructed prompt from Step 4
- ```
resolution
```
  : from Step 5
- ```
steps
```
  : from Step 5 (recommend 10-12)
- ```
shift
```
  : from Step 5
- ```
random_seed
```
  : from Step 5
- ```
seed
```
  : specific seed if
```
random_seed
```
  is false
Record the returned seed value for reproducibility
Note the generation time

预期结果： A generated image with recognizable ornamental forms and visible color. The color may not perfectly match the specified palette — this is addressed in evaluation.

失败处理： If the MCP tool is unavailable, verify that hf-mcp-server is configured (see

configure-mcp-server

troubleshoot-mcp-connection

). If the generated image is entirely abstract, the prompt needs more specific structural language — return to Step 4. If colors are completely wrong, front-load the color names in the prompt.

第 7 步：Evaluate Color Fidelity

Assess the generated image against five criteria, extending the monochrome rubric with color-specific evaluation.

Polychromatic Ornament Evaluation Rubric:
┌─────────────────────┬───────────────────────────────────────────────────────┐
│ Criterion           │ Evaluation Questions                                  │
├─────────────────────┼───────────────────────────────────────────────────────┤
│ 1. Palette Match    │ Do the colors in the image approximate the specified  │
│                     │ palette? Are the named colors present? Are there      │
│                     │ unwanted colors that break the palette?               │
├─────────────────────┼───────────────────────────────────────────────────────┤
│ 2. Color            │ Does the color distribution roughly follow the        │
│    Distribution     │ 60/30/10 allocation? Is the dominant color actually   │
│                     │ dominant? Does the accent appear sparingly?           │
├─────────────────────┼───────────────────────────────────────────────────────┤
│ 3. Rendering Style  │ Does the image look like the specified rendering      │
│                     │ style? Does a "glazed tile" look glossy and flat?     │
│                     │ Does "illuminated manuscript" show gold and vellum?   │
├─────────────────────┼───────────────────────────────────────────────────────┤
│ 4. Period Accuracy  │ Would this design be recognizable as belonging to     │
│                     │ the specified period? Are motifs period-appropriate?   │
│                     │ Does the color usage match period conventions?        │
├─────────────────────┼───────────────────────────────────────────────────────┤
│ 5. Form-Color       │ Does color clarify the ornamental structure or        │
│    Balance          │ obscure it? Can you "read" the motifs through the     │
│                     │ color? Does color follow form as intended?            │
└─────────────────────┴───────────────────────────────────────────────────────┘

Score each criterion: Strong (clearly meets), Adequate (partially meets), Weak (does not meet)
Note specific observations for each criterion
If 4+ criteria score Strong, the design is successful
If 2+ criteria score Weak, return to Step 4 for prompt refinement

预期结果： A scored evaluation with specific observations. Color ornament is harder to control than monochrome — expect Adequate scores on first generation for palette match and distribution.

失败处理： If most criteria score Weak, the prompt may need fundamental restructuring. Common fixes: move color names to the very beginning of the prompt, use fewer colors, specify the ground color explicitly, increase steps to 12.

第 8 步：Iterate or Finalize

Refine the design through targeted iteration or accept the result.

Color-Specific Iteration Strategies:

Palette correction: If colors are wrong, put specific color names at the start of the prompt: "turquoise blue and gold: [rest of prompt]"
Distribution correction: Explicitly state proportions: "mostly turquoise blue with small gold accents"
Rendering correction: Strengthen the rendering style description: "in the style of Iznik ceramic tiles, glossy glaze surface"
Seed-locked color tuning: Keep the seed, change only the color description to adjust palette while maintaining composition
Mood shift: Change "vivid saturated" to "muted antique" or vice versa to adjust overall color intensity

Iteration Budget: Limit to 3 iterations per design concept. Color iteration often requires more prompt adjustment than monochrome.

If the evaluation in Step 7 indicates specific weaknesses, apply the corresponding correction strategy
Regenerate using Step 6
Re-evaluate using Step 7
Accept when 4+ criteria score Strong or iteration budget is exhausted

预期结果： Improved color fidelity after 1-2 iterations. Perfect palette match is unlikely — aim for "recognizably in the right color family."

失败处理： If iteration is not converging, the color palette may be too specific for the model to reproduce reliably. Simplify to fewer colors (3 instead of 5), use broader color descriptions ("warm earth tones" instead of specific hex values), or accept the closest approximation.

第 9 步：Document the Design

Create a complete record of the final design for reproducibility and reference.

Record the following:
- Period: Historical period name and date range
- Motif: Primary motif(s) used
- Rendering Style: Painted, illuminated, glazed tile, etc.
- Color Palette: Each color with its role and approximate hex value
  - Dominant: [color name] (~hex) — 60%
  - Secondary: [color name] (~hex) — 30%
  - Accent: [color name] (~hex) — 10%
  - Additional: [color name] (~hex) — detail/metallic
- Color Harmony: Approach used (period-authentic, complementary, analogous, triadic)
- Color Mood: Muted, balanced, or vivid
- Final Prompt: The exact prompt that produced the accepted image
- Seed: The seed value for reproduction
- Resolution: The resolution used
- Steps/Shift: Generation parameters
- Evaluation: Brief notes on the five criteria scores
- Iterations: Number of iterations and key changes made
Note how the generated palette compares to the historical reference palette
Note any color-specific observations (colors that the model handled well or poorly)
Suggest potential applications and color adaptation notes (e.g., "palette would adapt well to screen display" or "would need adjustment for CMYK print")

预期结果： A reproducible record with full color documentation including hex approximations and palette analysis.

失败处理： If full documentation feels excessive, at minimum record the final prompt, seed, and a list of intended vs. actual colors. These allow reproduction and palette adjustment in future iterations.

验证清单

常见问题

Relying on color names alone: "Blue" is ambiguous — specify "turquoise blue," "cobalt blue," or "ultramarine blue." Different blues evoke entirely different periods and moods
Too many colors: More than 5 colors in a prompt confuses the model and produces muddy results. Historical ornament typically uses 3-4 colors plus a ground. Restraint is authentic
Ignoring the ground color: The background/ground color is as important as the motif colors. Cream vellum, white ceramic, gold leaf, or dark stone ground fundamentally changes how all other colors read. Specify it explicitly
Color without structural basis: Adding color to poorly structured ornament does not improve it. If the monochrome version does not work, adding color will not help — fix the structure first using
```
ornament-style-mono
```
Anachronistic palettes: Bright magenta, neon colors, or candy pastels do not belong in historical ornament. Pigment availability constrains period palettes — respect the constraint for authentic results
Insufficient steps: Color detail needs more inference steps than monochrome. Using 8 steps for color work often produces washed-out or imprecise palette rendering. Use 10-12
