Luckily I never had to match corporate colors of different models in ConTeXt...
the worst are colors specs with 4 decimals based on some design made in

decimal betweenm his sample and the one generated by tex
I have 16bit grayscale images where the full dynamic range contains very useful
information. Of course, no display really shows this and I doubt that any
printer would faithfully reproduce it, yet the eye can discern the difference
using the proper media. This is now called high dynamic range imaging in
photography... but has been used in X-ray imaging for quite some time now.
given that the average male can only see 16 shades of gray ...
For reasons of quality or transparency, rather free dissemination of
information, it would be useful to be able to distribute a PDF including these
images with their whole 16bit dynamic range. Of course, any or most all PDF
readers would only display 8bits, but one could in principal extract the
underlying image for examination and analysis.
c m y k in 16 bit would mean 4 * 8 bytes per pixel
(ok, one day we migh twant to store raw images made by these multi-ccd
(in high end) phone camera and do all these sharp and zoom corrections
outside that device .. interesting techniques btw)
