Lecture 21: Intro to Color Science (29)

Why is the fluorescent wavelength so focused? In all other light forms you have a mixture and here it's heavily focused on green and orange.


I think it's interesting that the wavelength actually doesn't decide the color we see. So the same color can be created by different combinations of rays with different wavelength.


I think for daylight, LED and incandescent, their energy is spread in a wide range of colors so in most of the case we perceive them as white light (although some may be slightly bluish or reddish). As for fluorescence, it often appears as pure green/blue/orange, so the intensity distribution is more focused




I'm surprised the warm white LED isn't more centered in the 650 area


It's interesting how daylight is more centered around blue and green!
