I must say, I'm with the original poster. Not so much because it bothers my eyes. More so because I can't use colors anymore. They all look too dark and therefore pretty similar to each other. I played with the options for hours and the only thing I like is light grey with almost no color.
I just don't see why we can't have a full palette of colors to choose from. My display lets me view millions of them. PT8? Not so much.
There's pages and pages of feature requests (most of them small but incredibly useful) on the DUC that went completely ignored in this new version and I can't recall anyone asking for a GUI overhaul.
