help to change colour background of a page

Site URL: https://monmonidesigns.com.au

I know this may be simple to some but I can not seem to be able to change the background of a page from a gradient to just a plain colour. 

The page I am concerned about is the Portfolio page.  

Can someone please let me know how to do this.
