custom gamma settings Hey, I have an imperfect solution that I use for this: in you Mac systems preferences, create a custom color profile in your Display preferences (System Preferences --> Display --> Color). Just play around with the different options until you get the color you want. I named my profile "higher gamma". Now whenever I am playing a game in parallels that appears too dark, I switch my Mac color profile to the higher gamma profile. Hope that helps, and if you find any other solutions I'd like to know.
