DirectorHal Sutherland had a kind of color blindness that is often cited as contributing to various color issues in Star Trek: The Animated Series, such as in "The Slaver Weapon", which features the pink-colored craftTraitor's Claw, and in "More Tribbles, More Troubles", in which the tribbles are also pink. ("Drawn to the Final Frontier - The Making of Star Trek: The Animated Series", TAS DVD) According to D.C. Fontana, the pink coloration of the Kzintiship in "The Slaver Weapon" was a result of Hal Sutherland being color blind, and thus unable to discern them as anything but shades of gray. [1] However, storyboard artist/character designer Bob Kline laid the blame on color director Irvin Kaplan. "Pink equals Irv Kaplan," shared Kline... "Irv was in charge of ink and paint, coloring the various characters and props (and he would do it himself in his office, he would sit down with a cel and paint it). He was also referred to by many people there as the purple and green guy. You'll see it in a lot of scenes, purple and green used together – that was one of his preferences. He made dragons red, the Kzintis' costumes pink. It was all Irv Kaplan's call. He wasn't listening to anyone else when he picked colors or anything."
