Enfold Health Demo – where to edit the colors?

I have downloaded the Health Demo and want to change the colors, especially the greens. They don’t change when I try to edit the theme in General Styling in WP. I can do each page manually (edit cell, tedious) but want to change them at template leve, and across the entire site. Checked out all the css files in the theme folder as suggested in the help files but can’t find any code that I could change. Please can anyone guide me in the right direction? Thank you so much in advance.
