When I put together a fish list for my 65g, part of the criteria was that each fish needed to be a different colour - we wanted all the colours of the rainbow, to make up for the fact that there would be very few/no corals in the tank.
So far, you've got grey/yellow (naso), red/white (firefish), purple (firefish), black & white (clowns), pink/green (sixline), yellow (tang), and to me the one thing that stands out is there's nothing blue. Blue corals are hard to come by, so I'm willing to bet your tank would really colour up with the addition of a blue fish or even a small school.
How about a damsel, or blue chromis, or - if you're willing to risk it - a cherub pygmy angel? Cherubs are more of a purple-blue colour, but the edges of their fins are a stunning electric blue.
