I was inactive for some days, and I missed this "heated" argument about the color of the icon 🙄😀
In a way I understand Konstantin, the grey colors make the icon "disappear" or looks inaktive. The same applies for the file tree in the dialog boxes. I guess Geoworks saved resources in the system by designing it this way, but maybe they also wanted to be true to the design guidelines made regarding interfaces from Rank Xerox, with grey, white and black as the basic colors? Look at Apple and MacOS, very consistent, and careful of the color pick in their UI, even if they also did some changes, with adding that fainted blue color in the UI, and the traffic lite LEDs in the window handling.
I suggest that we try Konstantins proposal making it yellow in the alpha and beta and make a decision later on, at the end of the beta? The same applies for the file tree in the UI.
