The Color Picker gives you any colour's HEX, RGB and HSL codes instantly, with one-click copying — plus a palette of ready-made colours to start from. It is the bridge between 'that green' and the exact code a designer, developer or thumbnail tool needs.
What is the difference between HEX, RGB and HSL?
They describe the same colour three ways. HEX (#0d7377) is the web standard for code and design tools. RGB (13, 115, 119) is how screens mix light. HSL describes hue, saturation and lightness — the easiest to adjust by feel ('same colour, but lighter').
How do I get the colour of something in a photo?
This picker works with colours you choose or codes you type. To sample from an image, open the photo in an editor with an eyedropper, note the HEX it reports, and type it here to get the other formats.
Do I need to sign up or install anything?
No. The Color Picker is completely free, needs no account and nothing to install — it runs in your browser, and anything you type stays on your device.
