The Philips delta shadowmask CRTs used in almost all 60s and 70s color TVs here in europe had uniformly white phosphor dots, surrounded by a very reflective aluminium matrix, this combination made for an extremely reflective screen
Early (1975 to 1979) Philips 20AX series in-line CRTs had the same white phosphors and the same reflective aluminium matrix of their delta shadowmask tubes (and they also still needed convergence adjustments)
some later (1979) Philips 30AX series "self-converging" in-line CRTs had the phosphors stripes tinted in pale but very distinct red, green and blue, with the same aluminium matrix
Philips used this combination of pale tinted phosphors and reflective aluminium matrix until the early 90s when they finally switched to darker phosphors and black matrix.
