As Neomancer was suggesting, you can not apply transparency to 2D objects, only to 3D objects. To achieve your desired effect, create a 3D quad (or use a sprite, but a quad is better) with your desired texture/color then apply EntityAlpha to it.
There are several GUI libaries available which use 3D commands. Check out the toolbox page.
