Can't figure out how to make background blue

http://www.residentialpm.com.au/about-us

I'm using the Corporate2 template.
I like blue background on the Header fields and would like to setup this same background color on Top6 or other fields.
How do I do this?
It appears that someone was able to do this on the website link about but I've been unable to duplicate.
Any help would be greatly appreciated.
Cheers

In module settings > advanced options > module suffix enter " blue" with empty space in front.
In your example link user is using " color" module suffix.

See you around...
