tweak to color balance after talking with colin and testing other software, lift for values above 1.0 was too intense.

 Use: 1 + ((lift-1) * (lift-1)) so 2.0 is still a full lift but 1.x isnt so strong.

Changed color picker to give more precission, we were having to edit the buttons to see what the numbers were.
