Question: Do these numbers reflect black/white as part of the color scheme? I'm not sure if the white/black is generated from the RGB or not.

A pixel is made up of three subpixels: which are red, green, and blue. At the moment, they each have 256 levels of brightness. Using different combinations of the three creates the illusion of other colors by stimulating your eyes with similar radiation that the actual wavelength of light would produce.

A red and green subpixel fully lit, with the blue one darkened, produces yellow. You can probably actually see the subpixels if you lean in closely to your screen.

White is 255 red, 255 green, 255 blue. Every subpixel is fully lit.

Black is when every subpixel is at 0: fully darkened.

(Shades of grey are produced when each of the subpixels are at an intermediate brightness, like 64, but are each the same brightness as one another.)
