How the palette is chosen

Close shades are grouped together and the biggest groups are shown, largest first, with the share of the picture each one covers. That gives you the colours a person would name, rather than thousands of nearly identical values.

The palette is sampled from a smaller copy of the image, so a large photo stays quick. Clicking reads from that same copy, which can differ by a shade from the full-size original on a very detailed picture.

How to use Colour Picker

  2. Choose your options

Questions

How do I get the hex code of a colour in a photo?
Add the photo and click the spot you want. The hex and RGB values appear underneath, and one click copies the hex.
How are the palette colours chosen?
Close shades are grouped together and the largest groups are shown first, with the share of the picture each covers. That gives the colours a person would name rather than thousands of near-identical values.
