Color Differences/Descriptors
Each color coordinate is identified by
a letter
—e.g., L*, a*, b*, etc. In this
example, CIEL*a*b* color differences
are displayed.
The component color
differences reported will
indicate if the difference is
positive (+) or negative (-).
The exception is DE, which
is always a positive number.
Pass/Fail
The Pass/Fail message indicates
whether the batch falls within all of the
color difference tolerances set for the

intervals of 10nm. Next to each
wavelength is the measured
reflectance.
