Color scheme would mostly be Solid colors Im looking at some pictures from the show and I see lots of solid colors I don’t see many vivid or highlighted colors maybe it’s because solid colors and solid dark colors usually represent something that’s filled with some seriousness . But because they are teenagers with robots it seems they did add some hints of highlights to colors making them stand out also
I feel like its more appropriate to leave artworks in a museum because if you leave them in their native settings it can possibly be destroyed or stolen. if you leave them in a museum it can be shown by lots of people who loved artwork and will pay billions to get one.
