Not so long ago, owning a black and white TV was a status symbol. Then color TVs came along, and someone invented a tinted screen with a parabolic lens that less affluent folks could attach to their b/w sets to simulate color – it had a brown tint on the bottom for dirt, blue on the top for sky, and a bizarre flavor of red/pink in the middle where the actors’ faces usually were – and it magnified the size of the screen. This cheap fixit was often better at rendering hues than the color TVs were, as the latter often gave the actors a distinctive fuzzy green complexion anyway.
At least Spock looked good.
