I don't think i clearly understand what color is on the molecular level... white light strikes a surface, and some of it gets reflected, and some gets absorbed, and you perceive the color based on what light gets reflected. That is ok, but what property of the material or the atoms that make it up exactly determines if light of frequency f gets reflected or absorbed?
Also, human eye has 4 rods, 3 for R G B, and 1 that apparently senses brightness. But can't you specify exactly every shade of color only using the 3 RGB components? Why do you need the 4th rod to pinpoint the color?
The second question is more of a biology question for fun, but mainly I am wondering about the first one.
thanks!
