Change line color unders slider

There are two lines under the slider. The home page title is in between the lines. How do I change the color? Thanks.

 

I also need to change the color of the line below the feature boxes.

 

Hello,

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

Code:

.slider-container {
border-bottom: 3px double your color value;
}
#content {
border-bottom: 3px double your color value;
}

 

Thank you.
