Color Palette Generator Online
Pull a color palette out of any image and check whether two colors pass WCAG contrast, all in your browser. Load a picture to read its main swatches as HEX, RGB, and HSL, or pick a single color to read and copy its values. Nothing is uploaded to a server and no account is needed.
Key features
- Extract a palette from an uploaded image - the sampling runs in the browser and each swatch copies as HEX with one click.
- Check the contrast ratio between two colors and see whether it passes WCAG AA and AAA.
- Choose a shade with the color box - the values and a live swatch update as you pick.
- Read HEX, RGB, and HSL for the same color side by side, so you can match whichever format your project uses.
- Copy any single readout to the clipboard with one tap, in whichever notation your project needs.
- Everything runs in the browser - no upload and no account.
When to use it
Reach for this when you have one color in mind and need its value in more than one notation - a HEX code for CSS, an RGB triplet for a canvas call, or an HSL string for a lightness tweak. Pick the shade once and copy whichever string the current file expects.
Privacy
The color you pick and the values it produces stay on your device. Nothing is uploaded and no account is needed. For converting between color formats in bulk, see the related developer tools.
