My skies are cyan instead of blue

b22c

Hi, I use standard picture control with -2 on saturation to achieve normal blues on the sky. If i use 0 saturation on any picture control I get cyan colored skies most of the time instead of normal blue. Anyone else get a lot of cyan colored skies?

Here's an example picture here:
