Richard Suchenwirth 2006-02-05 - This is a tweaked version of Colors with Names, which allows you to browse all colors with X11 names on a canvas, so that it runs in a PocketPC - I tested under eTcl in Sepp, but it should equally well work with other versions (not with Keuchel's though).

Scroll with <Up> and <Down> on the four-way button. Single-tap on a color to see its RGB value in hex (in the label below; double-click to copy to clipboard, so you can paste it in your colorful code :^)
