About RGB Color Theory

Well, it IS odd! When I was in the earlier grades, they spoke of using PRIMARY colors! RED, BLUE, YELLOW. Did you know that color tv CRTs(Used on pretty much ALL TVs until like 1980 and only recently all but gone) do NOT have yellow, OR white, OR black!?!?!?

THAT is why the first high quality color monitors were called RGB! Each letter was the first letter of the color the electron gun triggered. Red, Green, Blue!

TODAY, most printers don't have GREEN or BLUE, and the ONLY primary color they have is YELLOW! In fact, printers can't quite do black, so they include THAT also, which is why most printers are "4 color". Called CMYK (Cyan(ALMOST blue), Magenta(ALMOST red), Yellow, blacK(Black, probably called K to avoid looking like Blue))

HERE is a converter that looks like it should work:

RGB Color to PMS Colors - HEX color code to Pantone colour online converter, matching tool

BTW OBVIOUSLY all these methods mean it is impossible to communicate, etc... So some STANDARDS were derived. One of the more popular ones, at least when I was younger, was pantone. You could simply specify the pantone color equivalent, and a printer or hardware company could replicate it. If ONLY they had the same thing for house paints and carpets!
