Actually, on a closer examination,  Mail's Help Panel text color gets
dithered on Color Station.  There are actually two kinds of pixels
(RGB) = (51, 68, 136) and (RGB) = (51, 68, 153).  The former gives
B=0.5333 and the latter gives 0.6.  So, it's not a 12-bit pure color.
You've got to pick the color on a NeXTdimension to get the correct
information.

But there are more pixels of the latter in a unit area, though :->
