Color Displays
Some vector monitors are capable of displaying multiple colors, using either a typical shadow mask RGB CRT, or two phosphor layers (so-called "penetration color").
Atari used the term Color Quadrascan to describe the shadow mask version when used in their video game arcades.
In the penetration tubes, by controlling the strength of the electron beam, electrons could be made to reach (and illuminate) either or both phosphor layers, typically producing a choice of green, orange, or red.
Tektronix made color oscilloscopes for a few years using penetration CRTs, but they apparently weren't in great demand.

Famous quotes containing the words color and/or displays:
“Painting seems to be to the eye what dancing is to the limbs. When that has educated the frame to self-possession, to nimbleness, to grace, the steps of the dancing-master are better forgotten; so painting teaches me the splendor of color and the expression of form, and as I see many pictures and higher genius in the art, I see the boundless opulence of the pencil, the indifferency in which the artist stands free to choose out of the possible forms.”
—Ralph Waldo Emerson (1803–1882)
“The emancipation of today displays itself mainly in cigarettes and shorts. There is even a reaction from the ideal of an intellectual and emancipated womanhood, for which the pioneers toiled and suffered, to be seen in painted lips and nails, and the return of trailing skirts and other absurdities of dress which betoken the slave-woman’s intelligent companionship.”
—Sylvia Pankhurst (1882–1960)
