% ---- Adding two colors (subtractive) with n parts of color one and k parts of color two ----
% Actually, you get green from mixing (subtractively) yellow and cyan.
% Yellow is red + green (255, 255, 0), cyan is green + blue (0, 255, 255).
% Now make their opposite colors: blue (0, 0, 255) and red (255, 0, 0).
% Mix them additively and you get purple (255, 0, 255).
% Make its opposite and you get green (0, 255, 0).
% In other words, you can get a subtractive mix as the opposite of the additive mix of the opposites of your two colors.
% Finding a complementary color is very simple in the RGB model:
% For any given color, for example, red (#FF0000), you need to find the color, which, after being added to red, creates white (0xFFFFFF).
% Naturally, all you need to do, is subtract red from white and get cyan (0xFFFFFF - 0xFF0000 = 0x00FFFF).
