Hi John and Austin,
I think both of you are correct (when looking at iCal "Version 6.0 (1639)" with 10.8.1/ML).
Thanks!
The "very subtle grey in Month view" is visible on my iMac as well, but ONLY in Month view.
This (almost invisible) highlighting is not shown in Week view. In my initial question, I was addressing Week view (without mentioning).
This is inconsistent - one may hope that Apple will fix this (and also the "invisibility").
Maybe, some extension programmer has already generated a tool to modify these settings of iCal?
(And at the same time removes the terrible "leather look" of iCal? Yes, I know there are descriptions how to change the resources. But I would prefer a tool that allows to modify the "skin" of iCal and Contacts via a GUI.)
Bests, BW

The tools allows to remove the "leather skin", but does nothing to highlight sundays or weekends in iCal's Week view.
