Dear Dominik,
I list below some sources for the study of colour semantics in premodern India. Besides these, there are sections in the kośa-s as well as texts of alaṅkāra that deal with the polysemy of colour terms. I have written about the semantics of several individual colour terms in (fairly exasperating) detail in my PhD thesis, which is (as yet) asūryaṃpaśyā. Apologies for the inconsistent format of citation.
May I add, I benefited much from the references in footnote 72 in the volume ‘Studies on Indian Medical History’ that you and the late Jan Meulenbeld edited, and your students may find them helpful as well.
Warm regards,
Naresh Keerthi
