Isn't it also used for Apartheid?

Here is an interesting thing: (Please read slowly and carefully)
You always know about how to distinguish color from black and white, of course. But why?? This is because black (0 0 0) and white (255 255 255) are 2 of only 6 colors that all colors are based on, the others are red (255 0 128,) yellow (255 255 0,) green (0 255 128,) and blue (0 0 255.) These 6 colors are the psychological primary colors. (Look up primary colors at http://dictionary.reference.com if you want to see how they are used.) This set of colors is much less well-known than the traditional primary colors (red, yellow, and blue) or the light primary colors (red, green, and blue,) and was first identified in 1874 by a theory called the opponent color theory. All colors can be thought of as being on 3 scales, the "black-white" scale, the "blue-yellow" scale, and the "red-green" scale. This explains why some colors can be mixed to form new colors, but certain pairs "cannot" (actually, they can; the mixture is just gray.) Colors that produce gray when mixed are called complementary colors. Black and white are complements, as are red and green, as well as blue and yellow. I've been wondering if anyone can soon be creative and make some pictures entirely in either blue and yellow or red and green. Please note the following rules:
For making pictures in blue and yellow, the colors you use are the exact same blue and yellow that most people familiar with RGB think of: 255 255 0 for yellow and 0 0 255 for blue.
For making pictures in red and green, you must use colors that are slightly less yellow than the "red" and "green" that most people familiar with RGB think of: 255 0 128 for red and 0 255 128 for green. The colors that are used as "red" and "green" are actually somewhat orange-ish and lime-ish.

[edit] Black and white filters
Is there any (non-electronic) device to convert a color image to black and white? In Shadow of the Vampire, the filmmakers were such a thing to see what is being actually filmed. --Error 02:05, 9 October 2005 (UTC)
Well, you could shoot either the negative or slide the image is recorded on, or a print of the image, with a camera loaded with black and white film. That should give good results if you have a color slide, and a macro lens.
[edit] Shindler's List
Shouldn't Schindler's List get a special mention here, being consistantly rated as one of the greatest films of all time etc? —The preceding unsigned comment was added by 146.171.16.9 (talk) 03:45, 24 January 2007 (UTC).
[edit] Newspapers
The majority of newspapers, according to this article, had color photographs by the LATE 70s? Er, I lived through the late 70s, and not too many newspapers that I saw had color photos. And I had been all over the country. I remember that one of the Dallas daily papers had color photos here and there in the late 70's, but I didn't see any other newspapers that had them.
I'll research it, but I don't believe that the MAJORITY of newspapers had color photos until, AT THE EARLIEST, the early '90s.
P.S. Remember that popular old childhood joke? (I was a child in the 60s and 70s). What's black and white and red (read) all over? A newspaper! I guess that kids don't tell that one, anymore! Slater79 14:53, 1 February 2007 (UTC)
[edit] Use in dream-sequences
No mention is made of the film-standard of using black & white for shooting dream sequences is films and television, nor of the commonly held (though probably erroneous) belief that most people dream in black & white. (I think there's a bit of cause-and-effect here, in that the film/TV standard for shooting dream sequences in black & white has made people believe that this is actually the case in real dreams, possibly contrary to their own experiences.) At any rate, it'd be interesting to see a discussion of this added to the article. Unless there's a separate article for black & white specific to films? (This article does seem to be heavily weighted towards still photography, rather than motion pictures.) Lurlock 14:32, 4 April 2007 (UTC)
