Gcolor3 is a color selector and picker written in GTK+ 3. It is much alike Gcolor2, but uses the newer GTK+ version to get better integrate into modern desktop.

Gcolor3 enables you to pick the color from any pixel on your screen. It also offers a palette, so that you can easily mix and match a couple of colors together.

When you have found the perfect combination of colors, naturally you want to save them. Gcolor3 allows you to conveniently save and retrieve colors.

By releasing version 2.4.0, Gcolor3 now is “Color Picker” with a new maintainer, a new icon, lots of new improvements, and many translation updates.
