Maybe, but I think that we'd've evolved a way around it - probably doable in terms of the distribution of the different cones in the eyes. One thing that stands out to me is the relative rarity of blue in nature. Compared to red, a blue colour is far more likely to be sourced from the sky, rather than a source up close. It's not unreasonable to think that there might be a bias toward perceiving more probable structures, similar to (but far less extreme than) what occurs with the hollow face illusion.
