  If I'm not a normal user of latex, what about me ?


latex calls spot colours "named colors" because "named" seemed a more
generally understandable name than "spot" and because Americans have an
aversion to the letter "u".

Of course the top level user level documentation never says what any
specific driver does with the colour specification, and the dvips for
example just maps them to cmyk colours within its PS preamble, and some
other drivers convert them to cmyk or rgb within the TeX .def customisation
layers for that driver. However there is nothing to stop the .def code
for a driver producing code that allows colour separation, If I recall
correctly only the textures.def file does that in the standard
distribution.

The set of names defaults to those names known to dvips, but an option
to use pantone colour specifications was always a possible extension.
