colorize

pbakaus/impeccable

Add strategic color to monochromatic designs for better hierarchy, meaning, and visual engagement.

What is colorize?

The colorize skill introduces purposeful color to interfaces that lack visual warmth or personality. Use it when designs feel gray, dull, or need more expressive visual hierarchy. It guides you through assessing color opportunities, planning a cohesive palette, and applying color semantically across states, accents, backgrounds, and typography while maintaining accessibility and restraint.

  • Assess current color state and identify strategic opportunities for color introduction
  • Plan a cohesive color palette aligned with brand and context (2-4 colors max)
  • Apply semantic color for state indicators (success, error, warning, info)
  • Introduce accent colors to primary actions, links, icons, and interactive elements
  • Add subtle tinted backgrounds and surfaces to replace pure grays
  • Implement colored borders, dividers, and focus indicators for visual structure

How to use colorize

  1. 1.Invoke /impeccable to establish design context and gather the Context Gathering Protocol
  2. 2.Assess the current color state and identify where color adds value (hierarchy, meaning, emotion, wayfinding)
  3. 3.Ask the user to clarify color preferences or brand colors if unclear from codebase
  4. 4.Plan a color strategy with 2-4 colors max, defining dominant (60%), secondary (30%), and accent (10%) usage
  5. 5.Apply color systematically: semantic states first, then accents, backgrounds, borders, typography, and decorative elements
  6. 6.Test contrast ratios for WCAG compliance (4.5:1 for text, 3:1 for UI components)
  7. 7.Verify the result improves hierarchy, clarity, engagement, and accessibility without overwhelming the design

Use cases

colorize FAQ

How many colors should I use?

Choose 2-4 colors maximum beyond neutrals. Use the 60-30-10 rule: dominant color (60%), secondary (30%), accent (10%), with neutrals for structure. More colors create chaos; strategic color beats rainbow vomit.

What if I don't know the brand colors?

Ask the user directly to clarify brand colors and design guidelines. If none exist, choose colors appropriate for the domain and audience context (e.g., trust-focused = blues, energy-focused = warm tones).

How do I ensure accessibility with color?

Maintain WCAG contrast ratios (4.5:1 for text, 3:1 for UI components), don't rely on color alone (use icons/labels too), and test for color blindness. Avoid pure gray text on colored backgrounds; use darker shades or transparency instead.

Should I use pure black and white?

Avoid pure black (#000) and pure white (#fff) for large areas. Use OKLCH for perceptually uniform color scales, and add subtle tints to neutrals (warm or cool) for sophistication.

What does semantic color mean?

Semantic color assigns meaning: green for success, red/pink for error, orange/amber for warning, blue for info, gray/slate for inactive. This helps users instantly understand states and categories without additional explanation.

name: colorize description: Add strategic color to features that are too monochromatic or lack visual interest, making interfaces more engaging and expressive. Use when the user mentions the design looking gray, dull, lacking warmth, needing more color, or wanting a more vibrant or expressive palette. version: 2.1.1 user-invocable: true argument-hint: "[target]"

Strategically introduce color to designs that are too monochromatic, gray, or lacking in visual warmth and personality.

MANDATORY PREPARATION

Invoke /impeccable — it contains design principles, anti-patterns, and the Context Gathering Protocol. Follow the protocol before proceeding — if no design context exists yet, you MUST run /impeccable teach first. Additionally gather: existing brand colors.


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?
  2. 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, ask the user directly 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

  • Accent borders: Add colored left/top borders to cards or sections
  • Underlines: Color underlines for emphasis or active states
  • Dividers: Subtle colored dividers instead of gray lines
  • Focus rings: Colored focus indicators matching brand

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 sophistication
  • 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?

Remember: Color is emotional and powerful. Use it to create warmth, guide attention, communicate meaning, and express personality. But restraint and strategy matter more than saturation and variety. Be colorful, but be intentional.
