Give black tape max power to enable more composing

[ryanve]

Before if you did class="tape-pink tape-black" then tape-black would be inert and you'd have black on pink same as if you had just tape-pink. This change affords composing class="tape-pink tape-black" to make pink on black without adding any additional code. #winning =)
