Students are asking me for readings for their essays, and I'm slightly stumped for good suggestions on these two.  Can anyone point to some good studies of these topics?   

I am particularly interested in colour readings in relation to the health sciences and alchemy, but anything will do!  I know about Martha Selby's 2005 "Narratives of Conception" article and its remarks on red/white distinctions in ayurveda.

Regarding the senses, I haven't yet checked the Brill encyclopedia, and I will.  Probably there's something in Dasgupta, Hist. Indi. Philosophy.

Any suggestions will be much appreciated.

Best,

Dominik
