Some colour images cannot be produced by most of todays video and game screens but the illusion of them could be introduced without adapting the technology.
Film makers and game designers know pretty well were an audiences' eyes are focussing a majority of the time and could use a series of negetive colours in a given segment of screen during a film that when no longer present cause the viewer to percieve the opposite for a time afterwards even if that colour is not possible in RGB.-- 2 fries shy of a happy meal, May 25 2011 ???
With modern techniques, there are very few colors visible to the human eye that can't be reproduced by RGB; and even if you could find a way to put them on the screen, how much would it really enhance the viewing experience? Also, I'm not sure that using negative-space contrast (I think that's what you're proposing, anyway) to form lingering ghost-images is a very good idea: wouldn't the fuzzy blob of color in the veiwer's perception just blot out whatever images appear in subsequent frames?
Or maybe I just don't understand this idea at all...-- Alterother, May 25 2011 No you got it. The lingering ghost-images are very luminescent but they don't really blot out subsequent scenes. They would need to be used artfully to accentuate those later scenes.
This would be much simpler to tinker with in cartoon format or with CGI than a live action film, but then that would be the whole challenge.-- 2 fries shy of a happy meal, May 26 2011 //there are very few colors visible to the human eye that can't be reproduced by RGB// Depending on how you define different colours, there are infinitely many, or at least thousands.-- spidermother, May 26 2011 To repeat myself from elsewhere on here, RGB is wholly inadequate for violet and indigo. All it manages to do is produce some kind of weird purply mixture which looks very unnatural and for some reason reminds me of sweeties - artificial colour sort of thing.-- nineteenthly, May 26 2011 It's a great idea, which could be supplemented with lingering after-images of colour reversal effects.-- xenzag, May 26 2011 random, halfbakery
