Once you have provided us with your URL, we will be happy to assist you with everything. Please also tell us which buttons you would like to change the colors of.
In the meantime if you are comfortable with CSS you can the following example as a guide.
.x-btn.x-btn-real {
box-shadow: 0 0.25em 0 0 #a71000,0 4px 9px rgba(0,0,0,0.75);

If you change the hex color value then you can change the color of the 3D portion to whatever you like.
