Just to give you a taste of what I'm working on, here is my chosen color palette:
If I were to add any more colors, it would be a nice red. I think that may be the only thing lacking. But, I didn't want to totally overwhelm myself right out of the gate.
I had to include my three favorite colors: Olive green, purple and teal. I keep returning to those colors again and again. Occasionally, I want to fight the urge to use them, since they stand out/don't blend in/are unique, but then I remember that is exactly why I love them so. Sometimes, it's hard to be different, but if we were all the same, the world would be a very boring place indeed!
