Ah you're playing Mac, yeah, you're going to run into buggy things because the game needs permission to over-write files (which is what happens when you create your character), and Mac seems to be very averse to that. I'm glad you found a solution to it though. Do you think you can write out the steps you've done to get the game to work so I can let other Mac users know?
I'll give you a tip with matching; colours are grouped. You don't need to match the exact colour, as long as it's in the same group. So all yellows, reds, oranges, blues, greens etc. are all grouped and will work. So it doesn't matter if it's a light yellow colour or a dark yellow colour that you pick, both should work :) This should make things easier.
