Random color generator

Generate a random color

How the random colors are made

Instead of picking three random RGB numbers, which gives a lot of muddy colors, the generator picks a random hue, lightness and chroma in OKLCH, a perceptual color space, then converts the result to sRGB. The mood filters set the lightness and chroma ranges: pastel is light and soft, bright is vivid, muted is grayed and dark is deep.

Every color is named after the closest named color, so a random #7FB3D5 is described as the nearest familiar name rather than just a code.

What to use a random color for

• Breaking a creative block: start a design, illustration or brand exploration from a color you would not have chosen.
• Placeholder and test data: give charts, avatars or tags distinct colors.
• Games and classroom activities: draw a color and name, mix or match it.
• Palettes: for five colors that work together, use the palette generator, which randomizes whole harmonious palettes.

Random color challenges

1. Draw a random color and design a poster, logo or room around it.
2. Draw three random colors and find a way to make them work together, adjusting only lightness.
3. Use a random color as an accent on an otherwise neutral layout.
4. Name the color before you look at its name, then compare.
5. Try to mix it with paint: the color mixing chart shows what common paints make.
