Logo Prototype #2

A new logo prototype. It matches my business cards. I designed it myself. I wanted simple. This seems simple enough.

I'm thinking I might want to change the white box around the colors to be a little thicker, or just not there at all. Maybe changing the colors a little to be brighter. The green more yellow, and the blue-green a bit more blue, and the red a bit brighter red.

What do you think? Suggestions?
