You Are Not Prejudiced
Not only are you color blind, but you're also ethnicity blind, gender blind, and sexual orientation blind.
You don't judge someone until you truly know them. And even then, you're probably reluctant to judge.
You try to treat everyone equally. Everyone has a fair chance with you.
Good job - there's not a prejudiced bone in your body.
I voted "Sometimes" on the feeling nervous in a neighbourhood of a mainly different ethnicity, but that's cos I'd feel left out/different myself.
