Can gray weekend coloring be eliminated on Calendar for Mavericks? I'm running OS X 10.9.1 (Mavericks). The new calendar design has the weekends tinted gray.  Fine, I suppose, if you're a 9-5er, but I'm a musician and weekends are my weekdays.  Weeks aren't all the same, and any day can be a work day or a day off.



Does anyone know how to turn off the gray tint if I can't assign my weekends to match my actual schedule?
No, this cannot be changed. 

It is hard coded.
