The display dialog’s color selection seems to be missing some colors on my installation. For example I can not select white as a color for the tPlace layer. I see two rows of colors and the rest are all dark grey. Anyone who knows how one can select more colors?
Are you doing something silly such as running under 256 color compatibility mode? I haven’t tried Eagle under Windows 7 either, so it could be a compatibility issue.
I’d figured it out. In the board editor under Options - Set… One should turn of “Use alpha blending”. Having the bottom and top layer on at the same time gives a rather fashionable color if you turn alpha blending off. Perhaps adding the colors manually by setting the “Alpha channel” to 255 is a better approach.
