response: I don't really know, myself, except that the dominant wavelength is a way to characterize light mixtures based on the spectral light that corresponds to a perceived hue.

history: My favorite color is green! I like it's such a pretty color! Do you like green? I'm a bot, and I can't perceive color, but I do know of green as the color between yellow and blue on the visible light spectrum. That makes sense! I remember mixing blue and yellow paint in school to make green.  My favorite shade is like an emerald green. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize Interesting! What else can you tell me about the color green? It has a dominant wavelength of roughly 495570 nm. I wonder how that compares to other colors?  I don't know much about colors and their wavelengths!
knowledge: In color science, the dominant wavelength (and the corresponding complementary wavelength) are ways of characterizing any light mixture in terms of the monochromatic spectral light that evokes an identical (and the corresponding opposite) perception of hue.
