With a click on the 'COL' buttons (the ones showing RGB) a menu pops up with three colorpicking fields and a palette. The fields are the three planar intersections of a HSV cube, each allowing choosing in the field without the field changing. The palette is 'modal' unfortunately (couldn't find a simple working other method) where the button "paste to color" denotes the state that click in palette copies to edited color, and "copy to palette" means the active color is copied into the palette... Todo: - saving of palette in file - decide whether ESC leaves without changes...
