Overview
- The Empire Strikes Back screenplay introduces Yoda as a “bluish” creature.
- Early concept art and 1980 tie-ins, including the novelization and Marvel’s adaptation, portray Yoda in blue or purple hues.
- Creature-effects artist Nick Maley says the puppet was already green when he joined in 1979 and that dyes were mixed into the foam latex.
- Later printings of Marvel’s adaptation were redrawn so Yoda matches the movie’s green appearance.
- Lucasfilm and Disney did not comment, and the deaths of key early contributors leave the exact rationale undocumented.
