They don't need to be diametrically opposed. You just need a scheme that allows for the channels to be separated by filters. That simply means that you need to isolate the image across the red, green, and blue pixels (phosphor or LCD filters). Red/cyan works because one channel is pure red, and the other is split across green and blue. But red/blue, red/green, green/blue single channel combinations work well, too. Red/blue is more common than red/cyan, and red/green used to be popular. By using red/cyan, three common types of glasses are supported, however.
