Free Palettes and Hex Codes

Palette Vault is a free color reference for designers and developers. Browse ready-made four-color palettes, or open any named color to get its hex, RGB, HSL and OKLCH values, a scale of lighter and darker versions, and contrast figures against white and black. The tools do the making: build a palette around a color you already have, extract one from a photo, combine a photo with its colors into a shareable image, and check whether a pair of colors is actually readable.
