The actual home kit youve pictured has black shorts - Manchester United play in white shorts as their first choice, and black socks as the first choice, with white socks the first choice in European Matches.

I would classify the pink kit with grey shorts and socks as an away kit, especially since I (and probably most people) consider pink and red different colours. Man U have change kit styles that are almost as Iconic as the home (All blue, white shirts with black shorts), so I don't think this would work.
