eli5 what is the color grey

745 views

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.

The easy but I’d that the colors aren’t binary, but proportional.

The colors you outline are different combinations of different levels of the three component colors. To get purple, you have all or equal red and blue and no yellow. To get orange you have lots of red and some yellow and no blue. To get shades or hues of those colors, change the proportions.

White is the “full on” of each of the component colors, and black is the “full off” of them. The gradients of grey come so of the “equals” of all of the component colors. When all of the colors are equally “half on,” you get a district grey, not too bright or dark. Changing them equally will give you different shades of grey, while changing them slightly off but close to even will give you different hues.
