- Choose a scheme. Try complementary for high-contrast accents, analogous for calm interfaces, or monochromatic for tone-on-tone designs.
- Lock and regenerate. Lock the swatches you like, then click Regenerate Unlocked or Random Palette to explore variations.
- Export your palette. Copy the palette as CSS variables, a Tailwind config snippet, SCSS variables, or JSON.
Color theory in 30 seconds
Complementary
Two opposite hues on the color wheel. High contrast - great for CTAs and brand marks.
Analogous
Three neighbouring hues. Calm, cohesive, and reliable for content-heavy interfaces.
Triadic
Three hues spaced evenly around the color wheel. Vibrant and balanced; best when one hue dominates.
Tetradic
Two complementary pairs. Rich and varied - keep one color dominant to avoid visual noise.
Monochromatic
Variations of a single hue at different lightness and saturation values. Elegant and minimal.
Split-Complementary
A base hue plus the two hues adjacent to its complement. High contrast with less tension.
Shades
Pure color mixed with progressively more black. Useful for moody dark UI.
Tints
Pure color mixed with progressively more white. Soft pastels for friendly UI.
Frequently Asked Questions
What is a color palette generator?
A color palette generator is a free online tool that creates harmonious sets of colors based on color theory rules like complementary, analogous, triadic, and monochromatic relationships. NitroClaw's generator builds export-ready palettes for CSS, Tailwind, and SCSS in one click - no signup required.
How many colors should a palette have?
Most professional design systems use 5 to 7 colors: a primary, a secondary, an accent, plus a few neutrals for backgrounds, surfaces, and text. Five-color palettes are the sweet spot for landing pages and brand identities because they offer enough variety without becoming visually cluttered.
Which color scheme is best for a website?
Analogous and complementary schemes are the safest defaults for websites. Analogous palettes feel calm and cohesive (good for content-heavy sites), while complementary schemes create strong contrast for calls to action. Triadic and split-complementary schemes work well for playful or creative brands.
Can I export the palette to Tailwind CSS?
Yes. The export panel includes a ready-to-paste Tailwind config snippet that adds your palette under theme.extend.colors. CSS custom properties, SCSS variables, and JSON exports are also available - one click copies the format you need.
Are these palettes free for commercial use?
Yes. Color values themselves are not copyrightable, so any palette generated here can be used freely in commercial websites, apps, marketing materials, or client work. No attribution is required.
How do I check color contrast for accessibility?
The built-in contrast checker pairs any two swatches in your palette and shows the WCAG contrast ratio with AA and AAA pass or fail badges. Aim for at least 4.5:1 for body text and 3:1 for large text or UI components.
