I started work on an Android-based trivia-like game. You basically pick a topic (eg. volcanoes) and get a random set of 10 questions out of a bigger pool.
I'm really struggling to pick a colour scheme, and also, to pick a style or theme to use -- every choice seems arbitrary at this point. I do have a "company" site and colour scheme, but I doubt if that would be the right choice here.
How do I decide which theme/style/colour-scheme to use?
