Outdated Acrylic Tub Surround

I know - you're all going to think I'm CRAZY for removing that beautiful wallpaper!!! But what I want to ask if anyone has painted an acrylic tub surround - I know there is Rust-Oleum Specialty Tub and Tile Refinishing kits, but they are only in white, biscuit, and almond. I have posted on Ask the Expert whether they can tinted but I'm pretty sure they can't.
