Engima Theme: Changing color

Hi all

site is: https://www.lowermainlandproperty.ca

I’m using the Enigma theme.

There is a light blue color in the background of nearly every textbook I haven’t been able to find (to change). I’m about done looking. It shows up behind the text “Let’s get you started” in the slider, it’s the font for “About us” and it’s icon (has a question mark next to it), it’s the color of the bar under “Our Services”, it’s the color of the “home” button navigation background, blog……. and so on.

Can someone please tell me where that color is hiding in the css so i can change it?
