Dude, when was
Wikipedia's page on linguistic relativity and colour terms created, and how did I miss it?[1]
I am going to haul out my undergrad semantics thesis - which was on that subject - and PDFify it so I have a reference for it. (Expect a link here at some point.) Possibly even write a follow-up covering recent research and giving some sort of conclusion, as my thesis was almost entirely a literature review, and now I have a DRA account at the University Library I can actually read recent papers.
It may be apparent that colour terms are something I'm interested in. :)
([1]: Answer to initial question: apparently 3 weeks ago, as part of a Spring 2009 project at Berkeley where students add to Wikipedia on sociolinguistic subjects. That is quite cool.)
