Not a terrible combination of colors, and I like the description as well.
Your Uniform is Gray and Red You are the last person that others would suspect of being a superhero. You are a very private person, and you don't meddle in the concerns of others.
You would be pretty reluctant about being a superhero, until you reached your breaking point. And no matter what, you'd remain anonymous!
You may try to stick to your own affairs, but you are always ready to step up when no one else will. You are highly energetic and passionate about changing the world.
You are a person of great courage and confidence. You never second guess yourself, and you are able to jump right into action when the time is right.
