Sorry, no...metamerism is when the color of an object changes depending on
the type of illuminant... that is, an object appears of a different color
when observed under sunlight than when observed under fluorescent
light. That is due to the different reflectance characteristics of
pigments with different chemical structures. But the effect described
(tinted B&W prints) is due to some printers making black out of the three
primary colors (yellow, cyan and magenta, in most cases). Better printers
do have an additional cartridge with black ink for that purpose. Or it
might be a small registration difference when the different dots are
layered over the paper. Take a look at the print under a good magnifying
glass...
The rest of your story is true, Ford did paint a Mustang with very
expensive paint ($500.00 /gallon), somewhere circa '95, for the 30 year
commemorative edition . The pigment responsible for the effect was a
man-made layered flake, similar to mica. Later on Jeff Gordon (an American
NASCAR driver) raced a Chevy painted with a similar paint, a few years
back, courtesy of DuPont.
