Color Palette Generator Free - HEX & RGB Colors

About this tool

Color theory rules for harmony (complementary, analogous, triadic) exist because these combinations are visually balanced - but calculating the exact hue angles manually requires knowing the color wheel math. This generator applies the rules instantly from any starting color.

Enter a base color and generate a full color palette - complementary, analogous, triadic, split-complementary, and monochromatic schemes - with HEX and RGB values ready to copy.

Where this tool helps

Generate a brand color palette from a primary brand color, find complementary accent colors for a website design, create a monochromatic palette for a minimalist design system, generate triadic color combinations for vibrant UI designs, find analogous colors for a natural and cohesive palette, and create tints and shades of a primary color for hover states and backgrounds.

• Generates 5 harmony types from any base color: complementary, analogous, triadic, split-complementary, and monochromatic.
• Outputs HEX and RGB values for each color in the palette - copy-paste ready for CSS and design tools.
• Useful for brand identity work, UI color selection, and design system definition.

The most common question is which color harmony to use. Complementary pairs (opposite on the color wheel) create high contrast and visual energy - good for calls to action. Analogous schemes (adjacent colors) feel natural and cohesive - good for backgrounds and content areas. Monochromatic is the safest choice for a polished, professional look.
