What's the difference between carmine and magenta?

Carmine


Definition:

Magenta


Definition:

  • (n.) An aniline dye obtained as an amorphous substance having a green bronze surface color, which dissolves to a shade of red; also, the color; -- so called from Magenta, in Italy, in allusion to the battle fought there about the time the dye was discovered. Called also fuchsine, roseine, etc.
