The space of functions R->R is infinite dimensional, so does that imply that the set of colors is actually infinite dimensional, and the 3 dimensions of RGB is a crude approximation for human perception? Are there any animals that can see more than 3 dimensions of color?


I'm a bit confused what the emission spectrum graphs are showing, for example for the cool white LEDS is this saying that the light emitted by the LED is made up of these all of these frequencies, with varying intensities? Or is it saying that an LED producing blue light will be brighter than an LED producing green light?


What makes different light sources unique? I'm confused about how different light sources can produce different emission/absorption spectrums, rather than just manipulating the intensity of a general light source (like daylight for instance).


Given the emission spectrums, how would the associated light sources be perceived by the human eye? Is there an easy way to encode this difference using computer graphics? For example, daylight seems to have lower wavelengths than warm white light, but are perceived similarly.
