This is a scheme that tries to allocate pages to minimize cache conflicts. More precisely : if a process need a page, the kernel tries to give him a page that will not conflict (that is to say will use a different cache set) with its actual set of pages. Some "academical" studies have shown that some gain are possible. However I do not now any successful real-life implementation of page colouring. Some time ago, David Miller (of sparc, ultrasparc and gcc-sparc64 fame) implemented a minimal coulouring support.
