Is White A Colour?

[Native American]

On the art side, white is a neutral (contrasting agent is a good one, per chishnfips). Probably most of you who do paint have to sometimes mix a variety of colors to duplicate a particular tint. White (like a heavy Titanium White w/ a lot of TiO2 in it) just changes the contrast level. A 50% red in the graphics world is simply 50-50 mix of red and white (pink is the result).

The basic color is not changed. Adding white to a tube of anything else doesn't change it to another color, per se, even though my kids will tell me that pink and red aren't even remotely related!

CMYK used in printing is a subtractive system, RGB used in color tv's or computer monitors is additive. Printing inks filter out certain wavelengths, letting the substrate being printed on reflect back what you see as being color. The substrate being printed on can affect the color, sometimes drastically. Being reflective, you can't see it in the dark, as there is no light to be reflected and filtered. Adding any 2 of the 3 CMY colors together at a 100% value gives you secondary colors, the RGB of an additive color system. 100% of all 3 gives you a color that is almost black, no ink filters out no light, letting you see the color of the substrate.

Tv's & monitors use the additive system of RGB. None of the colors gives you a nearly black screen. All 3 together gives you a white screen. Any two of the three together at 100% value gives you the CMY of a subtractive system.

Either system, white is your eyes perceiving all of the colors at once, either reflectivly or additively.
