Coolors

Coolors is a popular palette generator: hit the spacebar for a fresh scheme, lock the colors you like, and keep rolling — a coherent palette in seconds. When you have no idea where to start with interface colors, it's an easy on-ramp, with a contrast checker and image color extraction built in.

1. Drop in one brand color (or extract it from a logo image), lock it, and hit space to generate the companions.
2. Fine-tune individual swatches by hue and lightness.
3. Run the contrast checker to validate text readability before signing off.
4. Export as CSS variables or another format straight into code.

• Spacebar generation — iterate without leaving the keyboard
• Lock-and-tweak means the tool suggests, you decide
• A built-in contrast checker makes accessibility a by-product
• Extract palettes from images and export in a range of formats
