That's only on the colour wheel, in which they are opposites. The true negative of Red is cyan. I didn't say they were opposites, just that red and blue are often depicted as contrasting colours, like black and white (except black and white are actually negatives of each other). I'm kinda going with a Yin/Yang theme here. If not Red/Blue, then Black/White instead, but I think that Red/Blue also represents how 'colourful' our fandom is.
