MinnFlier, I notice there is very little difference between the upper and lower wing, won't it be difficult to determine the orientation of the plane in flight?

I question this, as I wanted to make my upper and lower wing black and white but feel that perhaps there should be some difference between the two. I used to fly alot when I was younger, and am just getting back into the hobby with my son. I am sure he will see the plane fine, but my eyes are not what they used to be
