I can't find a place for much colour since these icons aren't very colourful to begin with, so it may not be the best choice in that respect. osu!mania currently has no icon (?) so I don't have anything to vector for that.
I'll have to come back to this since I'm out of time to work on it right now. I appreciate the advice.
