Coolors generates five-color palettes with a press of the spacebar. You can lock colors you like and keep generating until the rest of the palette fits. The tool also lets you extract palettes from images, check contrast ratios for accessibility, and browse thousands of palettes created by other designers. Palettes can be exported to Figma, Adobe tools, CSS, or images.

It is useful at the start of a project when you need a starting point for a color scheme, and also when you are refining an existing design and want to test variations quickly. The interface is fast and requires no account. For UI designers, brand designers, and developers who need to choose colors but do not have a formal design background, it removes a lot of guesswork.
