Red, Green, Amber? I'm going to assume you mean Red, Green, Blue, which is what additive display technologies use. RGB is used because it more or less divides the visible spectrum into equal parts, allowing it to create *most* of the colours that humans can see. Except human eyes don't quite work like that: http://upload.wikimedia.org/wikipedia/commons/0/04/Cone-fundamentals-with-srgb-spectrum.svg More sort of purple-blue, green-yellow, and orange. This discrepenancy between our eyes and RGB additive techniques does result in colours that your monitor/TV cannot create. I once found a persistence of vision image online that allowed one to see a colour shade that RGB cannot create. If I find it, I'll post it. |
Yes, you're right. I forgot green and red made amber. I just recall in my physics class that all colours are based off of those, hence why I don't understand the need for "better" colours because those 3 spectrums of light give you all colours.
