Most cultures in the galaxy place special meaning on the colors they can precieve. For an Many vehicles in the [[Ork]], red is regarded as the best. Many vehicles in the Ork armory are painted red as a result of the superstition that it makes them "'''''go fasta!'''''". Because of the cumulative psychic effect of the [[Waaagh]]!, this thought manifests itself as a real boost to the operation of a vehicle.

The effect is not limited to vehicles as red is found on just about any item an Ork wants to make strongastronger, fastafaster, shootz bettashoot better, etc.
