About Us
A free, private, browser-based toolkit for detecting and converting color.
Last updated: August 2026
ColorDetector is a free, browser-based toolkit for working with color. It started from a simple frustration: pulling an exact color out of an image usually meant opening heavy design software or trusting a random site to upload your picture to a server. We wanted something faster, more private, and genuinely useful for everyday work.
What we do
Our flagship tool detects the precise color of any pixel in an image you open, and reports it in every format you might need — HEX, RGB, HSL, HSV, CMYK, LAB and more. Around it we have built a growing set of converters, palette and gradient generators, and accessibility checkers that designers and developers reach for daily.
Privacy comes first
Every tool runs entirely inside your browser using standard web technology. Images you open are read locally and are never transmitted to or stored on our servers, and the colors you pick are never sent anywhere. There is no account to create. Like most websites we use Google Analytics to see which pages and tools are used, with IP anonymisation enabled — that is aggregate traffic data only, and it never includes your images or the colors you work with. Our Privacy Policy sets out exactly what that covers.
Who it is for
Designers matching a brand color, developers exporting CSS or Tailwind scales, students learning color theory, and anyone who has ever needed to know “what color is that?” will feel at home here. The tools are deliberately quick to load and work well on phones as well as desktops.

Yes. Every tool is free to use with no account and no usage limits.
