The package provides macros that emulate the ‘colour stack’ functionality of dvips. The colour stack deals with colour manipulations when asynchronous events (like page-breaking) occur; pdftex does not (yet) have such a stack, but dvips does, and the color package makes extensive use of it.

This package is an experimental solution to the problem, and works best with pdf-e-tex.
