Blue, Yoda originally was, archival Star Wars sources reveal

Review of screenplay, novel, and comics suggests film-makers made late decision to make diminutive Jedi master green

Reviews of archival sources - and new testimony from a special effects makeup artist who worked on the first Yoda puppets - suggest film-makers made a decision late in the development process to switch the character's skin colour to green.
