Quite the contrary actually, a blue wall REFLECTS blue light and absorbs other colors, and a red wall would REFLECT red light and absorb all other colors. That is why the wall looks BLUE or RED to the naked eye, because that is the only color temperature being reflected off the wall to your eye.
But like Justin was saying, you'd have to find the perfect hue to actually have some benefit. Would make for a very interesting experiment.
Edit: Haha, well as I think about it more, this would be very doable, but difficult. If some crazy grower actually wanted to take advantage of this, they would just have to paint a bunch of surfaces with different hues of red and blue, and compare the spectrums being emitted from the walls to match the best spectrum for your current stage of growth. I say someone tries it! As for me, I will stick with Mylar; definitely the best way to go!
