Change Color/Opacity of Folder Icons

Branch

Thanks to Scott for providing code so I could change the color/opacity of files name text on my home page. Is there a way to also change the color/opacity of the little folder icons beside the file names (to match the text)?

How to change color/opacity of folder icons???
The Mechanic helped me adjust the opacity/color of the folder names displayed below folder images with this CSS code:

.sm-user-ui .sm-tile-title a {
color: #FFC0CB;
opacity: 0.5;
}

Is there a way to do the same with the little file folder icons which appear next to the text? ? See www.branchimages.net
