Bar on Pages - Color change

Hi: I would like to change the color of the bar on each page to a light shade of grey. It is currently black. How can I do that? My website is michelelisasalon.com.

Thank you.

 

Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

Code:

.main-content .gallery h1, .main-content .page-content h1.contact, h1.single-heading, .page-content h1.page_title,.main-content .full-width h1.fullwidth-heading{
background:red;
}

Inplace of "red" put your color value.

 

Thanks so much!
