Does anyone know of a good book to understand colour theory/colour spaces/etc.?

I've been learning more and more about colour at both my job and just in my free time, but I don't really have a good grasp on all of these concepts. Does anyone have a good comprehensive book that covers all these topics? I don't necessarily need all the math behind things like gamma conversion, although perhaps that'd be beneficial as well.

Any input welcome, thanks in advance :)
