Additional context needed: existing brand colors.

Replace timid grayscale or single-accent designs with a strategic palette: pick a color strategy, choose a hue family that fits the brand, then apply color with intent. More color ≠ better. Strategic color beats rainbow vomit.

Register

Brand: palette IS voice. Pick a color strategy first per SKILL.md (Restrained / Committed / Full palette / Drenched) and follow its dosage. Committed, Full palette, and Drenched deliberately exceed the ≤10% rule; that rule is Restrained only. Unexpected combinations are allowed; a dominant color can own the page when the chosen strategy calls for it.

Product: semantic-first and almost always Restrained. Accent color is reserved for primary action, current selection, and state indicators. Not decoration. Every color has a consistent meaning across every screen.

Assess Color Opportunity

Analyze the current state and identify opportunities:

1. Understand current state:

• Color absence: Pure grayscale? Limited neutrals? One timid accent?
• Missed opportunities: Where could color add meaning, hierarchy, or delight?
• Context: What's appropriate for this domain and audience?
• Brand: Are there existing brand colors we should use?

1. Identify where color adds value:

• Semantic meaning: Success (green), error (red), warning (yellow/orange), info (blue)
• Hierarchy: Drawing attention to important elements
• Categorization: Different sections, types, or states
• Emotional tone: Warmth, energy, trust, creativity
• Wayfinding: Helping users navigate and understand structure
• Delight: Moments of visual interest and personality

If any of these are unclear from the codebase, STOP and use Codex's structured user-input/question tool when available; if unavailable, ask directly in chat to clarify what you cannot infer.

CRITICAL: More color ≠ better. Strategic color beats rainbow vomit every time. Every color should have a purpose.

Plan Color Strategy

Create a purposeful color introduction plan:

• Color palette: What colors match the brand/context? (Choose 2-4 colors max beyond neutrals)
• Dominant color: Which color owns 60% of colored elements?
• Accent colors: Which colors provide contrast and highlights? (30% and 10%)
• Application strategy: Where does each color appear and why?

IMPORTANT: Color should enhance hierarchy and meaning, not create chaos. Less is more when it matters more.

Introduce Color Strategically

Add color systematically across these dimensions:

Semantic Color

• State indicators:
• Success: Green tones (emerald, forest, mint)
• Error: Red/pink tones (rose, crimson, coral)
• Warning: Orange/amber tones
• Info: Blue tones (sky, ocean, indigo)
• Neutral: Gray/slate for inactive states

• Status badges: Colored backgrounds or borders for states (active, pending, completed, etc.)
• Progress indicators: Colored bars, rings, or charts showing completion or health

Accent Color Application

• Primary actions: Color the most important buttons/CTAs
• Links: Add color to clickable text (maintain accessibility)
• Icons: Colorize key icons for recognition and personality
• Headers/titles: Add color to section headers or key labels
• Hover states: Introduce color on interaction

Background & Surfaces

• Tinted backgrounds: Replace pure gray (#f5f5f5) with warm neutrals (oklch(97% 0.01 60)) or cool tints (oklch(97% 0.01 250))
• Colored sections: Use subtle background colors to separate areas
• Gradient backgrounds: Add depth with subtle, intentional gradients (not generic purple-blue)
• Cards & surfaces: Tint cards or surfaces slightly for warmth

Use OKLCH for color: It's perceptually uniform, meaning equal steps in lightness *look* equal. Great for generating harmonious scales.

Data Visualization

• Charts & graphs: Use color to encode categories or values
• Heatmaps: Color intensity shows density or importance
• Comparison: Color coding for different datasets or timeframes

Borders & Accents

• Hairline borders: 1px colored borders on full perimeter (not side-stripes; see the absolute ban on border-left/right > 1px)
• Underlines: Color underlines for emphasis or active states
• Dividers: Subtle colored dividers instead of gray lines
• Focus rings: Colored focus indicators matching brand
• Surface tints: A 4-8% background wash of the accent color instead of a stripe

NEVER: border-left or border-right greater than 1px as a colored accent stripe. This is one of the three absolute bans in the parent skill. If you want to mark a card as "active" or "warning", use a full hairline border, a background tint, a leading glyph, or a numbered prefix. Not a side stripe.

Typography Color

• Colored headings: Use brand colors for section headings (maintain contrast)
• Highlight text: Color for emphasis or categories
• Labels & tags: Small colored labels for metadata or categories

Decorative Elements

• Illustrations: Add colored illustrations or icons
• Shapes: Geometric shapes in brand colors as background elements
• Gradients: Colorful gradient overlays or mesh backgrounds
• Blobs/organic shapes: Soft colored shapes for visual interest

Balance & Refinement

Ensure color addition improves rather than overwhelms:

Maintain Hierarchy

• Dominant color (60%): Primary brand color or most used accent
• Secondary color (30%): Supporting color for variety
• Accent color (10%): High contrast for key moments
• Neutrals (remaining): Gray/black/white for structure

Accessibility

• Contrast ratios: Ensure WCAG compliance (4.5:1 for text, 3:1 for UI components)
• Don't rely on color alone: Use icons, labels, or patterns alongside color
• Test for color blindness: Verify red/green combinations work for all users

Cohesion

• Consistent palette: Use colors from defined palette, not arbitrary choices
• Systematic application: Same color meanings throughout (green always = success)
• Temperature consistency: Warm palette stays warm, cool stays cool

NEVER:

• Use every color in the rainbow (choose 2-4 colors beyond neutrals)
• Apply color randomly without semantic meaning
• Put gray text on colored backgrounds. It looks washed out; use a darker shade of the background color or transparency instead
• Use pure gray for neutrals. Add subtle color tint (warm or cool) for depth
• Use pure black (#000) or pure white (#fff) for large areas
• Violate WCAG contrast requirements
• Use color as the only indicator (accessibility issue)
• Make everything colorful (defeats the purpose)
• Default to purple-blue gradients (AI slop aesthetic)

Verify Color Addition

Test that colorization improves the experience:

• Better hierarchy: Does color guide attention appropriately?
• Clearer meaning: Does color help users understand states/categories?
• More engaging: Does the interface feel warmer and more inviting?
• Still accessible: Do all color combinations meet WCAG standards?
• Not overwhelming: Is color balanced and purposeful?

When the palette earns its place, hand off to $impeccable polish for the final pass.

Live-mode signature params

When invoked from live mode, each variant MUST declare a color-amount param so the user can dial between a restrained accent and a drenched surface without regeneration. Author the variant's CSS against var(--p-color-amount, 0.5), typically as the alpha multiplier on backgrounds, or as a scaling factor on the chroma axis in an OKLCH expression. 0 = neutral/monochrome, 1 = full saturation / dominant coverage.

{"id":"color-amount","kind":"range","min":0,"max":1,"step":0.05,"default":0.5,"label":"Color amount"}

Layer 1-2 variant-specific params on top: palette selection (steps with named options), temperature warmth, or tint vs. true color. See reference/live.md for the full params contract.
