Change color of misc. lines

I would like to change the colors of the lines depicted in the two attached photos. i.e one separating the slider from 3 feature area and the one above the widget area. Please advice

 

Hello,

Paste the code given below in Custom CSS section
(Appearance -> Theme Options -> Styling Options -> Custom CSS) of your dashboard.

Code:

.content-container {
border-top: 6px solid yellow;
}
.footer-wrapper {
border-top: 5px solid red;
}

Please change color according to your requirement.

Thanks & Regards
