I haven't tried pipe with color chemistry, but ABS (at least) works fine with B&W. I'd expect ABS to be okay for color as well; it's the same stuff some commercial plastic tanks are molded from (it's sold, conveniently in black, as drain pipe in sizes from 1.5 inches up to something like 6 inches, though in North Carolina the smaller sizes seem not to be in the home improvement stores).
