Most (all) acrylic has a protective sheeting on it to prevent scratching. The last I bought had blue on it. It was almost completely opaque. Not certain if they can cut it while it's still on there or not but I would think they could. Other possibility would be to wrap it in some type background material that the LFS sells.
And if you go plexiglas, I think the sell it tinted but I'm sure more expensive.
