Which tool do you actually need?

Five tools, one question each. If you can name what you are holding - a screen, a file, a number, a decision - the row below tells you where to go.

The EyeDropper API that screen picking depends on is not implemented in Firefox, Safari or any mobile browser. Where it is missing, take a screenshot and use the Image Color Picker - it needs nothing more exotic than a canvas.

Nothing you work on leaves this device

Every tool here is a piece of JavaScript that runs inside your browser tab. The image you drop into the Image Color Picker is decoded by the browser's own File API, drawn onto a canvas, and read back a pixel at a time. There is no upload step in the code, no account to attach a file to, and no server-side copy of anything. The same applies to the Color Picker: the EyeDropper API returns one color to the page and the page keeps it in that tab.

Your colors persist between visits through local storage on the machine you are using, which is why there is no sync feature and no reason to create one. Clearing your browser data removes them, and no one else can see them either way.

The honest exception is measurement: visiting a page sends its address and standard browser metadata to the traffic analytics this site loads. That is a page view, not your work. The exact list of what is collected and how it is anonymised is in the privacy policy.

How a color becomes three numbers

Screens make color by adding light, so every color you see is a recipe of red, green and blue. Each channel is stored as a whole number from 0 to 255, which gives 256 possibilities per channel and 16,777,216 combinations in total. That is the whole of what follows: HEX is simply those same three bytes written in base 16, so #ff5733 is 255 red, 87 green and 51 blue wearing a different notation.

HSL and HSV restate the same triple the way a painter thinks about it - which hue it is, how saturated it is, how light it is - which is why they are easier to reason about when you want a lighter or more muted relative of a color, and why converting between them rounds to whole numbers. CMYK is a different system entirely, describing ink that subtracts light rather than a screen that emits it, which is why a HEX-to-CMYK conversion is a formula rather than a translation.

Alpha - transparency - is a fourth channel, and adding it to a six-digit HEX produces eight characters: #ff573380 is the same orange at half opacity. If you want the arithmetic behind any of it, the Color Converter shows every notation for one value at once.
