wasn’t sure if i should post here or to nostupidquestions.
so i get that there 3 primary colors, Red, Blue, Yellow, combining them you get a secondary color.
add red and blue you get purple, add blue and yellow you get green, add yellow and red you get orange, combine all 3 you get brown.
So wouldn’t brown be a dark white or a light black since white is the presence of all color and black is the absence?
I think i also read somewhere that RBY only works for paint, but when it comes to atoms releasing photons, the three primary colors are RBG, in which case start from the top, go into the quantum chemistry if you need.

COLOR THEORY!
So all the stuff we see is a combination of two variables: frequency and intensity. (Mantis shrimp see more, dogs see less.). In our eyes we’ve got rods and cones. Rods can’t tell the difference between frequencies, but are more sensitive to intensity. They can see better at night, but with no color. The 3 (or 4 for freaks) types of cones absorb more Red, Green, or Blue. And from the mix of which cones are wiggling, we can identify the spectrum of frequencies which is visible light. This is what color is.
Radiation can come with a mix of frequencies, just like sound. Getting single pure frequency is actually kinda hard. White light is an even mix of all visible frequencies, with a lot of intensity. An even mix of frequencies with low intensity fades from white to grey to black. Blackness is simply no light, and none of our eyeball cells pick up anything. In total blackness, that sort of background hazy splotchy redness you see is your cells failing to sit still and wiggling on their own.
Grey is all the different frequencies of colors, but with an intensity of about half-way through human’s range of vision.
Brown is a low-intensity orange.
Atoms release photons with a variety of frequencies and different mixes of frequencies at different intensities, both within and without the visible spectrum. The RBY and RGB systems represent the visible spectrum in different ways, but fundamentally are both talking about the same thing: Frequencies and intensities. RGB lines up closer with the biology of our eyeballs.
Some people think that colors only exist inside our heads and it’s all a social construct, but they’re wrong.
