Neither of these are 'colors' in the usual sense -- the first is (I'm guessing)
a white value, and the second is an RGB triplet packed into a hex integer.
Please be clear and consistent in naming and implementation, and document in the
public API how the values of these constants should be interpreted.

(I'm fine with using the packed-hex values, but if we do that, then
kToolbarButtonTitleNormalColor should be 0x858585).

Sounds good. If we want to have consistency and not that many constants I think
using the Hex values is the best choice.
