I love the episode, despite its limitations. The only thing that rankles about it is the pink uniforms.
Edit: Well from the link someone left above I found this!!
The Traitor's Claw
(and the Kzinti space suits) was painted pink because the director of this episode, Hal Sutherland
, has a kind of color blindness
. D.C. Fontana later speculated that Sutherland had probably thought the pink color of the craft was a shade of gray. ("Drawn to the Final Frontier - The Making of Star Trek: The Animated Series
