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. Everything runs in your browser — no image or color is ever uploaded. Free for commercial and non-commercial use, with no attribution and no account.
Four-color palettes you can use as-is, browsable by mood or by color family.
Every named color gets hex, RGB, HSL and OKLCH values in one place.
A ladder of lighter and darker versions of any color, so you get a working light and dark variant instead of one isolated value.
Every color and swatch shows how it measures against white and black, before you commit to it.
