Marie Severin (1929-2018) joined EC as their first and only in-house colorist to work on Kurtzman's war books. She had no art schooling, no production experience, and was color-blind, but her bold and creative work immediately delighted Kurtzman. Her work ethic saw her develop enough skills that she went on to decades on staff at Marvel as a colorist and production artist, with many assignments as a penciller or inker including for Marvel's own MAD rip-offs, Not Brand Echh and Crazy magazine. Her last regular assignment before retirement saw her return to coloring, on DC's Superman Adventures from 1996 to 2002.
