Hi,

To change the background color of the content wrapper go to Appearance > Customize > WP Portfolio Theme Options -> Custom CSS and paste the below CSS code then click on Save button.

.post-main .post .entry-main {
	background-color: #fff;
}

change above #fff color to your own color.

For more color option and additional more options you can upgrade to the premium version of WP Portfolio theme which will be available very soon.

Thank you!
