The mint is a great colour. It looks good with the logo, and it makes the shirt a bit more interesting to look at. Black, though it does look great, is everywhere. EVERYONE has black clothes. Plus, in the summer, colours are more fun and aren't as hot hahaha That was my logic.
I like the mint and white. Although, I think I favor the white purely because of the gold symbol versus silver on the mint. I think the silver washes the shirt out a bit. I would enjoy the fun play on color if it were gold on mint maybe. All three are lovely though! I would gladly wear any of the three
