how change color under sidebar?

Hey there nowymm,

How are you doing today?

If this is the part that you want to change color to http://screencast.com/t/22HcBeFsuI in order to match background color you can do that with CSS.

Please try adding the following CSS code in the style.css file of your child theme or if your theme doesn’t have custom CSS tab add it in your site using the following plugin:

.col-2cl .main-inner {
    background: none;
}

Hope this helps 🙂

Cheers,
