Ozpin's eyes change at least twice in the series, Volume one they're gold, and Volume two they're grey. Someone else pointed this out on another thread, but I forget where. If you pay attention during Ruby's interrogation in Ruby Rose and then again in his close-up in Best Day Ever, you can see the color change.
