Maybe grey with yellow dotted lines is the way to go.

I've seen a lot of black cycling tops lately and thought the same thing. I was at a tri store recently, would see something with a really cute bright print on the front, just to turn it around and see an all-black back.

In daylight, black is actually more visible than light blue, light green or most browns, which blend right into sky and vegetation.
I'm trying to picture this, I am. Not feelin' it, but am open to hearing more.
