Change color of dropdown menu to match menu bar?

I have successfully changed the color of my menu bar but can't seem to figure out how to change the color of the dropdown menu.

Here's the code I entered in Styling Option/Custom CSS

#menu .ddsmoothmenu li li a {
background: #5B6EB0;
}

Also, what would the custom CSS to change the color of the "Read me" Button" and the rim of the Circles
Thanks

 

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

Code:

.feature-content-inner .circle{
background:red;
}
#menu .ddsmoothmenu li li a {
background: #5B6EB0!important;
}

It is not possible to change the color of read more button because it is a image, If you want to change it color then,Go to images directory present in your theme directory and replace your image with present read more image or edit it.

The name of image is "readmoreblue.png"

Note:- Use same name for your edited image and remove the current image.
