How to change the Jgive campaign Cell color?

First up amazing support team. Got most of my issue fix quickly.

I like to change the cell color a at the bottom of this page.

It is currently white text over white background. (See “Promoter other campaigns”).
I have copy single.php in the proper folder. Just little lost making the code change on single.php

I got this from tech support the same answer three times.
