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:
“The great God endows His children variously. To some he gives intellect—and they move the earth. To some he allots heart—and the beating pulse of humanity is theirs. But to some He gives only a soul, without intelligence—and these, who never grow up, but remain always His children, are God’s fools, kindly, elemental, simple, as if from His palette the Artist of all had taken one color instead of many.”
—Mary Roberts Rinehart (1876–1958)
“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)
