    There surely is no single answer. It depends on the phosphor in use, the electronics in the CRT, the age of the tube, and the settings on the individual unit. From memory, I would not describe any monochrome white tube that I ever used as 'reddish'. Commented 2 days ago

    This question is similar to: Exactly what color was the text on monochrome terminals with green-on-black and amber-on-black screens?. If you believe it’s different, please edit the question, make it clear how it’s different and/or how the answers on that question are not helpful for your problem. Commented 2 days ago

    Right, and what I had in mind was this answer showing a screen with bright white phosphors. Commented 2 days ago

    @dirkt - DEC VT05, VT50, VT52, VT100 were all white phosphors. Only with the VT220 was there a choice of white, green, or amber models. Pretty much all the non-DEC glass ttys I saw (Newbury, etc) were white too. DEC scopes such as on the PDP-1 and graphics terminals such as the GT42 were white; come to think of it, so was the CDC 6000 console. The canonical 'green screen' was in my experience just an IBM thing, and maybe Tektronics vector terminals. Commented 2 days ago
