The creator of Mega Man and former Capcom producer Keiji Inafune explained at PAX Prime why his iconic character is blue. Inafune stated that the development team wanted to create a blue character, but Inafune thought this was “gross”. However, the team explained to him that on the NES the colour palette for blue was a larger variety than any other colour so they could be more descriptive with the character design. Keiji accepted this and thought it would be interesting to have a uniquely blue robot.  Inafune says that he decided to change Mega Man’s colour when he gets new weapons as he felt it would be strange to have a blue robot shoot red flames.
