under abusive processing conditions. The difference in color between
these two processing conditions is then measured in dE* units using
the CIE L*a*b* color scale. Table 4.6 shows the process color change in
dE* units mapped between the gray and yellow color subclasses.
Visually, a larger change in color due to processing conditions can be
tolerated in a light yellow color than a gray color, as shown by this
mapping based on historical data.
