What is a Color Palette?
A color palette is a collection of colors that work well together, typically used for UI design, branding, web themes, or visual projects. Good palettes follow color harmony principles to create aesthetically pleasing combinations.

Color Harmony Modes Explained
Random
- Generates completely random colors with good saturation and lightness
- Best for: Exploration, playful designs, creative inspiration
- Use when: You want maximum variety and unexpected combinations
Analogous
- Colors sit next to each other on the color wheel (e.g., blue, blue-green, green)
- Creates harmonious, natural-looking palettes
- Best for: Nature themes, calming designs, professional UIs
- Use when: You want colors that blend smoothly without high contrast
Complementary
- Uses opposite colors on the wheel (e.g., blue and orange, red and green)
- Creates vibrant, high-contrast combinations
- Best for: Call-to-action buttons, energetic designs, attention-grabbing elements
- Use when: You need strong visual impact and color contrast
Monochromatic
- Single hue with variations in lightness (e.g., light blue, medium blue, dark blue)
- Creates sophisticated, cohesive palettes
- Best for: Minimalist designs, elegant branding, subtle gradients
- Use when: You want a clean, unified color scheme
Locking Colors
The lock feature lets you preserve colors you love while regenerating the rest:
- Generate a palette
- Click the lock icon (🔓) on colors you want to keep
- Click Generate again—locked colors stay, others regenerate
- Mix and match: Lock your brand colors, then generate complementary accent colors
Using Generated Palettes
In CSS/Tailwind
:root {
--color-primary: #3B82F6;
--color-secondary: #8B5CF6;
--color-accent: #F59E0B;
}
In JavaScript/React
const palette = [
{ hex: "#3B82F6", rgb: { r: 59, g: 130, b: 246 } },
{ hex: "#8B5CF6", rgb: { r: 139, g: 92, b: 246 } }
];
In Design Tools
- Copy HEX codes directly into Figma, Sketch, Adobe XD
- Use RGB values for print design or precise color matching
- Save JSON for programmatic theme generation
Tips for Great Palettes
- Start with 5 colors: Enough variety without overwhelming
- Use monochromatic for backgrounds: Subtle variations for cards, sections, shadows
- Use complementary for CTAs: High-contrast buttons stand out
- Lock your brand color: Generate accent colors around your main brand color
- Test accessibility: Ensure sufficient contrast for text (use a contrast checker)
- Save your favorites: Screenshot or export JSON for palettes you love
- Iterate: Generate, lock favorites, regenerate, repeat until perfect
