CSS Color Palette Generator
Generate a harmonious color palette from one base color - complementary, analogous, triadic, and more - with HEX/RGB/HSL values.
Pick a base color and a harmony type - this tool generates a matching palette with HEX, RGB, and HSL values for each color.
Contrast figures shown here are a quick reference, not a substitute for full accessibility auditing across your actual text/background combinations.
What Are Color Harmonies?
Color harmony rules (complementary, analogous, triadic, monochromatic) are ways of picking additional colors that relate mathematically to a base color on the color wheel, producing palettes that feel intentional rather than random.
Why Use This Tool?
Manually calculating complementary or triadic hues (rotating around the color wheel by specific degree amounts) is tedious by hand - this tool does the hue math and shows you the resulting palette immediately.
How to Use It
- Pick a base color.
- Choose a harmony type: complementary, analogous, triadic, or monochromatic.
- Copy individual color values (HEX/RGB/HSL) or the full palette.
Understanding Contrast Info
Where shown, contrast figures are a quick approximate reference for a color pair against white/black - they are not a replacement for full WCAG accessibility auditing across your actual real text and background combinations.
