i need a way to determine two things. first, the choice of color for the appearance, which on tiger (not sure about more recent os versions) seems to be one of two choices, blue or graphite. i'm not necessarily looking for the rgb value itself (although, in addition that would be nice), but rather the users choice. the second, however, i would like to determine the rgb value of the highlight color. how can these be accomplished? i poked around the appearance manager documentation, but didn't see these things specifically..
