How to use this tool in under a minute.

No account, no download — everything runs in your browser and nothing you pick is saved anywhere.

  1. 01

    1. Pick a hue and saturation

    Click or drag anywhere inside the wheel — or focus it and use the arrow keys (hold Shift for bigger steps). The angle sets the hue, the distance from center sets the saturation.

  2. 02

    2. Adjust lightness

    Use the slider under the wheel to move your color toward black or white without changing its hue or saturation.

  3. 03

    3. Choose a harmony

    Click through complementary, analogous, triadic, split-complementary, tetradic, or monochromatic to see which other colors the tool recommends alongside your pick — read what each one means on the Combinations page.

  4. 04

    4. Check contrast

    The contrast panel shows how your color reads against pure white and pure black, with a pass/fail against accessibility guidelines (WCAG AA) — useful if you're picking text or UI colors, not just art.

  5. 05

    5. Copy a hex code

    Click any swatch in the results to copy its hex code to your clipboard, ready to paste into design software, CSS, or anywhere else.

  6. 06

    6. Go fullscreen

    The expand icon opens the wheel in a larger, distraction-free view — useful on a big screen or when you want to focus.
