Lighting to bring out the colors in corals

[trilinearmipmap]

I bought a "Green bubble coral" at J & L, it looked greenish in their store, at home it looks pink.

I bought an "Electric Green Mushroom Rock" at Denman Pet gallery, it looked like bright neon green in their store, at home it looks green like a pine tree color.

The Ricordea I ordered from Ocean Aquatics looks like a mud grey color under my lights, I'm sure it is supposed to look purplish or blue or green.

My lights are 8 T5 bulbs: 4 x 6500 K, 2 x actinic, 2 x "Blue Plus".

If I swap out the 6500K bulbs for 10000K bulbs will this bring out my green colors better, also what will it do to the red colors in my tank?
