Color Picker

How Color Picker works

Pick the exact colour of any pixel in a photo and read it as HEX, RGB and HSL — useful for matching a brand colour from a screenshot. Everything happens inside this page: the tool reads your input, runs the calculation or conversion locally, and hands the result back to you. Nothing is transmitted, because there is no backend to transmit it to.

That design choice is deliberate. Most free tool sites upload your files to a server, process them there, and quietly keep a copy. Toolcin cannot do that — the site is a set of static files. If your connection dropped the moment the page finished loading, every tool would still work.

Reading a pixel, not guessing

The image is drawn onto a canvas at its original size, and each click reads the exact red, green and blue values of that pixel. There is no averaging and no sampling: what you click is what you get.

That matters when matching a brand colour from a screenshot. A colour that looks uniform on screen is often several slightly different values, and picking the middle of a flat area rather than an edge gives the intended one.

Three ways to write the same colour

HEX is what CSS and design tools expect. RGB is what the canvas returns and what most image editors show. HSL is the useful one for modification: keeping hue and saturation and changing only lightness gives you a tint or shade that still belongs to the same colour family.

Copying HEX is one click; the other formats are shown so you can read them without converting by hand.

Compression changes the colour

A JPEG that has been saved and resaved shifts individual pixels slightly. Two neighbouring pixels in a supposedly flat area can differ by two or three steps in each channel, which is invisible to the eye and visible in a hex code.

If exactness matters, work from a PNG or a lossless screenshot. If you must use a JPEG, click the centre of the largest flat area and accept that the value is approximate.

Good to know

• Works offline once loaded, including on flights and in locked-down networks.
• No file size limit beyond your device's own memory.
• Free to use, with no account and no usage counter.
• Results are produced locally, so they are not logged or shared with anyone.
