Sky color controls

I noticed the rotational direction of the sun affects the sky color, showing sun rise and sun set. Is there any script access to the sky colors? I feel like the sun has to be too low for the sky to be completely dark, so I’d like to customize it. Any ideas? Thanks!

Actually I just got on the asset store and bought Unity Asset Store - The Best Assets for Game Making . Seems to be what I was looking for and it appears to be working with beta 18. Haven’t tested it thoroughly but the sun position is realistic, thats all i care about.
