Online colour picker: HEX, RGB, HSL and CMYK
Pick a colour with the picker, with your browser’s eyedropper or by tapping a spot on one of your images. You will see that colour in HEX, RGB, HSL, HSV and CMYK, ready to copy, and whether it reads well on white, black or another colour according to WCAG.

HOW TO USE IT
Three steps.
Pick the colour
Use the picker, the eyedropper (if your browser has one) or open an image and tap the spot you want.
Copy the format you need
Each format has its own “Copy” button. You can also type a code and it is converted to the others.
Check the contrast
Compare the colour with white, black or another colour and see whether it passes WCAG levels AA and AAA.

Colour picker: common questions
Why does the CMYK not match my print shop’s?
It is a mathematical conversion with no colour profile. Print shops use the profile of their paper and inks, so the final CMYK may differ: use it as a reference.
Is the image uploaded anywhere?
No. The image opens in your browser to sample colours and never leaves your device.
What contrast do I need?
WCAG 2 asks for at least 4.5:1 for normal text and 3:1 for large text at level AA; level AAA asks for 7:1 and 4.5:1.
Are my images uploaded to a server?
No. The tool runs inside your browser: files are read and processed on your device and are not sent to Cocuyo or to any third party. You can check it in your browser’s network tools: your file is not sent.
Is it really free?
Yes. You can try it before signing up; to keep using it, we ask for a free account, with no subscription. It uses no credits and does not count toward your 30 welcome uses: it has no usage cap.
