I believe "cc" stands for "color class" (though "visual class" would have been
more consistent with X terminology). The value 3 comes from the X protocol
definition - the header file X11/X.h has:

#define StaticGray 0
#define GrayScale 1
#define StaticColor 2
#define PseudoColor 3
#define TrueColor 4
#define DirectColor 5

Cheers
