Auto-copy on pick

The instant you click, the color lands on your clipboard in your chosen format - HEX code, RGB, HSL and more.

Full color wheel

Fine-tune hue and saturation on a wheel, with lightness and alpha sliders plus editable HEX, RGB and HSL fields.

20-color history

Your last 20 picks are saved as swatches. Click one to reload and re-copy it - perfect for building palettes.

Click the icon
