This is not a definitive answer from a scientist but this is my theory. Red and blue filter out a picture that is a combination of two pictures, one for each eye. Since red and blue are on the opposite sides of the spectrum, it is more effective at filtering the other. I am assuming they don't use maroon and violet because maybe they like it to be a primary color or maybe using maroon and violet would darken the image too much requiring a much brighter screen. Opposite would go for let's say orange and green. Maybe they are too close on the spectrum and wouldn't filter out the other image as well. Orange might let more light through than green. Also, if you have ever looked at an image that has blue right next to red it is hard to focus on the point where the colors meet. So there is a definite physiological reason.

Why 3D has two color scheme?
The Red and The Blue? It matches with the two colour colours on the 3D-Glasses. What basically happens is your two eyes see a slightly different perspective of the world. The Eyes send the image as signals. The two images merge and your brain then reads these signals, to form the 3D image. With these glasses, your left eye sees red and your right sees blue. In the movie, the frames are painting in red and blue, with the red slightly to the left, and the blue to right. When you brain combines the red and blue, a 3D image is formed...

How do 3D cameras produce a 3D image?
There are two cameras next to each other and they are combined in a video editing program. They make one video coloured blue and the other red to give the 3D effect. That's why you wear blue and red glasses. Now they have these new glasses that are just plane black, I don't know how they work though.
