OK, this has nothing to do with OSC but I thought I'd ask anyway, since we're all intelligent here to give a good response.

This sound stupid, having been resolved somewhere else, but: isn't black and white a color? When you say there is a "colorless" tv show, it's in black and white, so does that mean that they aren't colors? So what does that make them? Being parts of different kinds of paints, crayons, and markers, doesn't that make them colors? I am so confused. [Confused]

Technically, white is the presence of all colors and black is the lack of all color.

With light and color reflection, a material will reflect the color that it is and absorb all the other wavelengths. So something that is green reflects the green light waves and we see green. Something that is white has all colors and so reflects all colors as white. Something that is black has no colors and absorbs all the light.

On the other hand, black is a mixture of all pigments, and white is the absence of pigmentation. For what it's worth.

:-p

Also, color is mixed into the broadcast signal differently. Black and white is merely the "brightness" or, as we say in the biz, "Luminance" portion of the signal. The colors are transmitted as a separate part of the signal, hence black and white broacasts are "colorless."
