Is it private and secure?
Your privacy is built in. Random Color Generator runs completely on your device, so whatever you enter stays in your browser and is never transmitted, logged or stored on any server.
Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.
You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.

Frequently asked questions
How do I generate a genuinely random colour?
Each generated colour comes with its HEX, RGB and HSL values ready to copy. Picking uniformly at random in RGB space is the simplest approach, though it clusters toward muddy mid-tones — constraining saturation and lightness produces a more usable spread.
Why do random colours often look bad together?
Because RGB is not perceptually uniform: equal numeric steps are not equal visual steps, so uniform random sampling over-produces dark and desaturated colours. Generating in HSL with a fixed saturation and lightness, varying only hue, gives a far more coherent set.
Can I generate a random colour that is readable on white?
Constrain lightness. For WCAG AA body text you need a 4.5:1 contrast ratio against the background, which in practice means keeping HSL lightness below roughly 45% on white. Check any candidate with the contrast checker before committing.
Is the randomness cryptographically secure?
It uses the browser's random source and is intended for design work, not for secrets. If you need unpredictable values for security purposes, use the password or random string generator instead.
