Thanks for making this suggestion. This is a much better solution than
creating a new syntax out of whole cloth, I should have known that Org
would already have a working solution in place.
Just for completeness I'm adding an example of a color handler which can
be added to a users config to enable colorization of exported text to
html and latex.
--8<---------------cut here---------------start------------->8---
(org-add-link-type
"color" nil
(lambda (path desc format)
(cond
((eq format 'html)
(format "<span style=\"color:%s;\">%s</span>" path desc))
((eq format 'latex)
(format "{\\color{%s}%s}" path desc)))))
--8<---------------cut here---------------end--------------->8---
it should be fairly straightforward to extend the above for background
or class link types

I think in-buffer colorization is much less important than the export
behavior.
