More specifically, UIColor and NSColor store a reference to a colorspace and a set of components (plus alpha). The colorspace defines the number of components and their meaning. So all of the RGB colorspaces define 3 components, Red, Green, and Blue, which means UIColor and NSColor need to store the color using those 3 components (plus alpha) whenever they're using an RGB colorspace. |
