Color Enhancing only 1 section of clip

[DVX100Shooter]

I have a clip where I want to boost the blues in the sky but keep everything else that way it is. What do I need to do to give the sky a bit more Blue but keep everything else in the shot normal or how I have it currently?

 

[Robbie Comeau]

try gooing to levels, or curves, and choose the blue option, and then boost it

Or create a key with the eye dropper.

If you have FCP Studio 2...use color's Secondaries "Room" and isolate the blues.
