The color picker works like this: it picks any color on screen via the browser eye-dropper, with HEX/RGB/HSL outputs and saved swatches. Everything happens on your device - the input never leaves your tab unless the tool clearly states it performs a server-side lookup.

Frequently asked questions
Which browsers support the eyedropper?
Chrome and Edge expose the native EyeDropper API; fallback manual entry covers the rest.
How does the screen eyedropper work?
It uses your browser's built-in colour sampler - click the pick button, then click any pixel on screen, and the HEX, RGB and HSL values land in the panel with a saved swatch.
Why does the eyedropper not work in my browser?
The sampler API is available in Chromium browsers - where it is missing, paste a HEX value or use the manual sliders instead.
