Negative colors are also part of the scRBG gamut. Anyway, to challenge 
what you say above. Below is a test that is part of a few test that I 
have done offline.

http://css-class.com/test/css/3/colors/experiments/color-merging2.htm

Some questions.

1. In the first example (the whitish area composed of red, lime and blue 
lines), why can I see red and then yellow before the whitish color?

2. In the first example (the whitish area composed of red, lime and blue 
lines), why can I see blue after the whitish color?

3. In the second example (the pinkish area where #797979 has replaced 
lime), why do I see a yellowish orange before the pinkish color?

4. When I print these out (Window 7, 64bit, standard LCD monitor), why 
does the first example look pinkish and the second example look grayish?
