Change background color of jetpack portfolio

Hi, is it possible to change the background color of the shapely/jetpack portfolio from black to another color (e.g., #933658)? My site isn’t live yet so I’m not able to share a link but I’ve attached a screenshot.

You can ignore/delete this post…was thinking I needed custom CSS but just remembered the color options are in the actual widget. :-/

I will close this case now, Feel free to contact us again if you have other questions Thanks!
