A color picker like that in Adobe Photoshop (source files)
You can easily choose a color and then drag it to the place where you need it: for example the Haiku Desktop, Insite Constructor, any text editor (insert as HTML hex code) and much more...
* You can collect up to 10 favorite colors which are restored the next time you start Colors.
* You get a color preview for text (text and background color).
* With an eye-dropper tool you can pick a color from anywhere on your desktop.
