We first see IG-88 here in the bounty hunter scene.
In the book "Tales of a Bounty Hunter" Boba Fett 'killed' IG-88 and he wound up here in the junk pile (next to the furnace). But for continuity, his color will have to be changed to match.
Ady's not gonna make a change based on an EU book. The book should have matched the movie.
