I could not do it the way I wanted to. But you get the idea. You want it to be effective ad or business card. You can do it with a light green back round and Really dark green letters etc. I once saw a guy who had a white truck with gold letters on it. That does not work too well. You can not see it. Now on a red truck yes but not white. Both colors are too light. Its good to have a design also. That helps customers identify with your company. Put you logo on everything from your shirts, trucks, letter heads business card etc.
