I talked with a staffer in terminal four who said there was a "red" m + f team that was in their "20's to 30's". They are Caucasian with the m being tall and the f being short. The staffer also saw a team that was "yellow or green". That team was 2 guys with sandy blonde hair.
I can rule out the 'yellow' since I saw a team that was "yellow" for sure.
I know the "red" team description is inconsistent with the twitter photo of two guys in red.
