injector color

Does the color of the injector denote the size in 4.6 engines? For instance, I am shopping intake manifolds and have seen yellow, orange, black and purple injectors on factory Ford intakes. What sized do the colors denote?
Any help would be greatly appreciated.

My guess would be flow per hour.

Were they Motorcraft injectors? Maybe they are a different color per car application?
