It feels as though you are forcing it, I think you should spend more time looking at sets to see how they mesh.
You'll also find suggestions to wait about a year before you pull the trigger on CPCs as your preferences will change dramatically within the first year, while you see what you like, what is meh to you. Meetup are also a great thing to do to find your way.

Some unspoken guidelines would be:
Don't over use or even reuse colors on chips

Cali (.05-100)
Vegas (.25-100)
