I did not say perceivable colours but displayable colours. > > I can send 16.7 million different RGB NUMBER combinations to a PowerBook > display but it will only display 518,733 different colours. This means that > 16,258,483 of the RGB numbers are basically "wasted". Lets take a hypothetical blue car under controlled day lighting and photograph it, then display it in the very best of monitors (with any necessary adjustment if you prefer), how many colours does the image on such screen display? Lets take a blue card, a yellow card and a red card, place them on a white background, again in a controlled lighting situation, photograph them, download such image in your super computer with super screen. How many colours do you perceive? How many colours do you perceive or able to count count in a typical black and white photograph? I am sure if you carryout this basic experiments it will become clear to you whether the world is that multi-chromatic, and most importantly whether you actually need all that extra gamut the cinema display offers if not for your "luxury" or if this is very harsh then your "choice". Oh, I should add that if your "GameBoy" displays such colours that you are pleased with, and you can reproduce them in a printing device what's wrong with that?
