Buying MH lighting. What is the best bulb spectrum for fastest growth and best color?

As the topic states. What is the best bulb spectrum for fastest growth and best color?

65k will get you the best growth, but it looks so yellow it is not too pleasing to the eye. I love a good 10k Ushio. Great growth, nice white/blue color to my eye. You could always add actinic as needed.

I think growth depends on type of corals you plan to grow under this light.
But best color - it is too subjective.

I plan on keeping zoos and sps.

SPS like 6500K, zoas - don't know
Like Amy said, 6500K have a bit yellow tint.
