color difference

color difference

The method of encoding color information in video/TV signals. The color difference signal designations are B-Y and R-Y, Cb and Cr, Pb and Pr, I and Q, and U and V. See YUV and YUV/RGB conversion formulas.

An absorbent article comprising: a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorbent body between the liquid-permeable top sheet and liquid-impermeable back sheet, wherein the top sheet exhibits a color difference in the range of 39-77, based on the L*a*b* color system and measured from a skin contact surface of the top sheet in a liquid dropping test, and the top sheet comprises a color-reducing agent having an IOB of 0.

Both of the above concepts depend upon using more sophisticated color models, color appearance models, for metrics of illumination quality rather than the fundamental models of colorimetry (CIE XYZ tristimulus values and chromaticity coordinates) and color difference metrics (CIELAB).
