Yes I know that Ubuntu has gone totally brown, but the tool bars, highlight clours and menus by default look greenish/brown to me. They aren't grey, or brushed metal, or pale blue, or tinted shades. The greens and blues are dead - there is no depth or vibrancy to them. This is the desktop that people see first up, or with the big push for Ubuntu, they get totally browned out. I haven't had a chance to look at Kubuntu but I have heard rumours that even Mark Shuttleworth is using Kubuntu as a more attractive desktop. Unsure of the theme choices, though.
