If you’re looking for something more advanced than those already listed (I have them all and each has it’s merits), then I think you’re going to have to jump into color science texts. Definitely not light reading... Some that I’d recommend-
Color Appearance Models by Mark Fairchild, ISBN 0-470-01216-1
Digital Color Management Encoding Solutions by Edward Giorgianni & Thomas Madden, ISBN 0-201-63426-0
Color and its Reproduction, Gary Field, ISBN 0-88362-201-7 (this one is more print oriented)
