Yeah I assume thats the thinking, but its usually as a result of not realising that the action master does have wings or just not following the colour switch pattern. Or now a days because of Botcons SG Thundercracker.
Yes, it would look more cohesive if the wings were the pinky purple colour. Or what if they would have been a completely different colour altogether - like neo orange! That would make him even more 90's awsome!
