Basically yes, look up additive vs subtractive colors... that's why for a monitor you need RGB, but ink cartrages are Cyan Magenta and Yellow

In short, colored light, and pigments work in opposite ways. Basically all visible light mixes together to make white light. Blue paint, basically absorbs the red and green light, allowing only the blue to bounce back... so mixing more colors of paint, means less light. until almost nothing gets out (hence black). But on a light source, more colors = more light, leading towards white.
Agreed, if it's true, I'd have to say if it's true it makes me respect Bruce Willis less. Either way why would anyone care to disrespect her in either situation... unless she were to be making a public figure of herself and claim all poor people are lazy or some crap.
