> And many people know that specific colors are really just wavelengths in the electromagnetic spectrum. [...] > There are many systems involved to turn an RGB triplet value into a specific wavelength of light I think this wavelenght-color connection, often perpetuated in high-school classrooms, confuses people more than helps. In particular when talking RGB colors, your display (or really, any part of the process) w…
That’s when you’re talking about color production (how the artist/content creator intends a specific visual image to be perceived). Color reproduction is 100% an engineering thing about wavelengths. To my knowledge monitors do indeed change the wavelength. Sure it’s several separate colored emitters, but using constructive and destructive interference to generate a wavelength doesn’t take anything away from it. There…
As an illustration for the in your head position: Human eyes can't directly perceive yellow tones. What we think of as yellow is a computation on the signals of both the M and L cones. If both say they perceived radiation at approx. the same intensity, that gets calculated as yellow afterwards.
That's why RGB displays are not reproducing the correct wavelengths, but only those our eyes can read directly: red, green and blue.
