Thanks guys. Thats is what I was looking for. The colors do blend to the point of being barely diferentiated. Add a little exaust stains, salt air, fuel, and sunlight, and the helo looks like it is one color. I'll wash out the grays a little and dirty it up so it looks "used".
I didn't know helos could be this much fun, and interesting! (tongue in cheek, and a bit "cheeky")
Thanks for your help. rangerj
