The themes range from mediocre (Iron Man), through terrible (most others), to so eye wateringly bad (Hulk) that it should never have been suggested. This wiki already has a theme and that is the imagery outside of the borders. It doesn't benefit from a garish clash of colours indiscriminately filling the infoboxes as well.
