If whites aren't white and or blacks aren't black when color is turned down then it's a grayscale issue. Screen controls primarily effect black, but there's also usually color drive pots to adjust grayscale balance of whites....Granted things varied in the inline gun CRT era (late 70s to 2000s) and inline sets are too new for my taste so I have almost no experience with them.
