I run a module at the University of Leeds called Colour: Art and Science. For me colour is a classic meta-discipline and understanding of colour requires and appreciation of ideas from lots of different academic fields. So I like to present a very multi-disciplinary perspective of colour and I have students enrol from all sorts of different departments in the University which is a lot of fun. One of the main reasons I run this blog is as a resource for those students.
So I was interested to just come across this Brief History of Colour in Art by Sarah Gottesman which covers some of the same stuff that I talk about.
In the same vein I came across this discussion by @CINEMAPALETTES about cinema colour palettes that shows how colours are used to set the mood of iconic films.
