This coloring page of Nute Gunray from the Star Wars universe is an interesting one. He is wearing a deep purple robe, and his expression is of disdain, as if he doesn't approve of something. To really bring out the character's attitude, I suggest using stark colors, like black and white, to contrast with the purple background. For Nute's robe, use a dark, rich purple to give it an air of authority, and for his facial features, use light colors to emphasize his disapproval. Additionally, by adding some green to the picture frame, a nice contrast can be created to emphasize Nute's strained expression.
