Oh! I'm glad that you caught this and posted your comment Julie! I was working on my tiny laptop at home last night and couldn't see the other colours in the attachment. When I opened it again just now on my 21" monitor at work the attachment was so much clearer!!
It sounds as though you have come up with a solution -- just make sure that the shading doesn't "over-power" the rest of the tactile.
