Coral+ dips into the red spectrum eliminating the need for a purple/pink/red bulb with the limit of a 4 bulb fixture. It is also one of the bluest of any daylight bulb (followed by KZ New Gen). That should get you the pop/color you are looking for while providing good growth as well. You also mentioned running LED supplement earlier. If you do run RB supplements I would definitely go with the option with no actinic, you won't need it.
