Change the border's color of a button in Unity3D

Question

I began to work with Unity3D since one month and I'm trying to do an application which contains a menu, composed by a panel and several buttons. At this moment, I'm trying to customize the menu, I change the fill color of the panel and buttons, but until now I could not change the border color of the buttons. There is any way to customize the border's color of the UI buttons? I would appreciate your help. :)
