Roland,
When it comes to the clear combs, I have tried everything my friend. The only way to get an OK look is to spray paint the back of it completely. Still doesn't really work because the honeycombs don't "light up" correctly.

Okay, I must confess that I never held that lenticular in my own hands or saw it in reality. So the front painting was just an idea. A bad idea as it seems. :lol
Another idea: Is painting of the colorless lenticular really necessary? I mean the board's color is pink. Wouldn't it shine through?
