Not receiving theme support for Aurum - Need help to change theme color

I purchased the theme: Aurum Version: 1.0 By CKThemes and have received ZERO support.

I need help changing all the aqua color throughout the theme to a different color. When I search for the color within the backend editor, there are many possibilities where this color can be found. I don’t want to screw up the code. Can someone help guide me in the right direction? Any advice would be greatly appreciated.

My site is:

The navigation, footer, social links, and blog all use the aqua color.
