Free Palettes and Hex Codes

Palette Vault is a free color reference that runs entirely in your browser. Picking colors is easy to start and hard to finish. You find a blue you like, then need three more that go with it, then a darker version for text, then you discover the pair you chose is unreadable. The site is built around those four moments. Browse ready-made four-color palettes by mood - pastel, vintage, neon, sunset, night - or by color family. Categories come from what a palette actually measures as, not from a label somebody typed. Open a color for its hex, RGB, HSL and OKLCH values, a scale of lighter and darker versions, contrast figures against white and black, and palettes built around it. The scale is the useful part: it hands you a working light and dark version instead of one isolated value. Use the tools to make rather than pick. Build a palette around your own color with per-swatch locking.
