Out of those choices, Hellrot (Imola Red would be great too) or Frozen MCB.
However, if it's at all possible, the color I'd really really want if I went Individual would be Techno Violet. It's unique, but definitely not too flashy. Please for the love of all that is holy pick TV. Pretty pretty please
