"New" colours possible?

For some years now I've wondered
-- whether the (red-green-blue-mixable) colours we know are all there are in
this universe, and if not,
-- whether it might be possible to neurologically change the visual cortex
(or whatever necessary) to create the sensation of other colours, and
-- whether there has been any research suggesting that other animals are
actually seeing different colours than we do.

I am neither talking of broadening the EM-spectrum we can see by changing
the eyes' perception (as this would supposedly simply distribute our known
"rainbow colors" over that new spectrum), nor of mixing pseudo-new colours
from the base colours that we already know. Also, I wouldn't consider any
eye-related limitations essential, as I really mean directly tapping into
one's brain.

I'd be glad to get any feedback, be it on physical possibility, neurological
practicability or philosophical thoughts. Thanks in advance for brightening
or dimming my hopes to see "Color X" before I die... ;-)

PS: Maybe someone even has information on people reporting previously
unknown ("unmixable") colours after having been under the influence of
drugs...?
