Desktop apps
The colour tools as a program you install, rather than a page you open. Everything runs on your own machine.
Palette Vault for Windows
Windows 10 and 11
A desktop colour toolkit. Generate palettes, pull them out of a photo, and pick a colour from anywhere on your screen. Works with no network connection at all.

- Generate four-color palettes across eight harmony schemes
- Reroll with the spacebar until something lands
- Drop in a photo and get the colors that define it
- Eyedropper reads any pixel on screen, inside the app or outside it
- Save palettes to a collection that survives restarts
- Click any swatch to copy its hex, or take all four at once
No account, no sign-up, no telemetry, and no network requests of any kind. Everything is computed on your own machine.

The same colour work runs in the browser without installing anything: see the tools on this site, or the browser extensions and the Obsidian plugin.
