four-color glossies
n.
1. Literature created by {marketroid}s that allegedly contains
technical specs but which is in fact as superficial as possible
without being totally {content-free}. "Forget the four-color glossies,
give me the tech ref manuals." Often applied as an indication of
superficiality even when the material is printed on ordinary paper in
black and white. Four-color-glossy manuals are never useful for
solving a problem.
2. [rare] Applied by extension to manual pages that don't contain
enough information to diagnose why the program doesn't produce the
expected or desired output.
