Garage Lighting

Background: 25 x 32 with 10ft sidewalls and 16' tall Peak.

I am installing the lighting and am trying to decide on a High-Bay fixtures to supplement the lighting in the shop.

What will give the best quality lighting Metal Hydride or High Pressure Sodium?

I am looking at these lights:

Isn't sodium the brownish looking light like you see on some street lights? I'd stay away from that as it would be hard to see true color.
