Abstract: The color properties of a white or nearly colorless fabric are represented by whiteness index (WI) or yellowness
index (YI). These two indexes relate to a white fabric’s color quality. The purpose of this study was to identify the properties
of WI and YI on the CIELAB through the simulations of estimation data for a systemization of color quality control. The
results indicated that the relationship between WI and YI was a negative correlation, however the coefficients of correlation
function between WI and YI were depended on hue. There were two hue transition points of the rate of changes in WI and
YI. These hue transition points were the reference points to divide the hue contribution to WI and YI. These points were not
the point of h=0 and h=180 and asymmetric. In addition, where the colors were same distance from the white point on the
CIELAB, the rate of changes in WI and YI by ΔEw were depending on hue. Specifically, when WI decreased, YI of reddish
and yellowish tinted colors decreased more than bluish tinted colors. |
