You could... not color it?
Ask a friend who has... no hobbies?
Or do it monochromatically? A good example would be The Ghosts of Oddville. Its all purple but still stunning. Maybe even more so, since it gives it a really unique feel.
Personally I love color, and I find it the easiest and quickest step. Everyone is different. (Lines are the worst for me, I hate lining and it takes forever.) If you're not confident in your ability to pick colors that look good together, less is always more!
