I haven’t played in a couple years but I remember changing the colors for the frames and background for the various UI windows. It appears that the new UI won’t allow these changes. Is there another way to do this or is it just disabled now?
Alphas are locked to the dark/black color scheme and the whole panel with the color options is blanked out. Omegas have the option to pick from a few color schemes that CCP thought would fit with EVE’s “dark and gritty” vision that they have. Honestly, the Alpha color scheme (dark/black) looks the best, everything else is diarrhea.
