Have you looked into naturally-coloured cotton at all?  This is
fiber that comes from cotton plants specifically bred to express
different colours, some of which are relatively saturated.  (A quick
google shows fibers available in, among others, a deep fawn/brown.)
As it's not dyed, it should behave as white cotton, and not be
vulnerable to solvents. If you check resources for handspinners, you
should be able to track down suppliers--possibly even seeds, if you
want to be really sure what level of processing (or lack thereof)
the fiber has undergone.
