Hue Angle Bin (numbered clockwise)<br />
R f<br />
R g<br />
R f,skin<br />
Analogous to CIE Ra (CRI). Characterizes the average color shift of the 99 CES to characterize the overall level of similarity between the test source and reference<br />
illuminant. Values range from 0 to 100.<br />
Compares the area enclosed by the average chromaticity coordinates in each of 16 hue bins to characterize the average saturation level of the test source compared<br />
to the reference illuminant. A neutral score is 100, with values greater than 100 indicating an increase in saturation and values less than 100 indicating a decrease<br />
in saturation. The range in values grows as fidelity decreases.<br />
Characterizes the similarity of skin tones (CES15 and CES18) as rendered by the test source compared to the reference source. Values range from 0 to 100. Rf,skin<br />
can be used to supplement other values when skin is an important consideration.<br />
Color Vector graphic<br />
Provides a visual representation of hue and saturation changes based on the average rendering in each hue bin, relative to the reference. The graphic provides a<br />
quick understanding of how different hues are rendered in different ways.<br />
Chroma Change by Hue Indices - Local Chroma Shi<br />
Provides numerical values for relative chroma change in each of 16 hue bins, which can be used to evaluate saturation (positive values) or desaturation (negative<br />
values) of yellows, reds, blues, greens, and in-between hues compared to the reference.<br />
Hue fidelity Indices - Local Color Fidelity<br />
Provides a numerical characterization of color fidelity in each of 16 hue bins, which can be used to evaluate how similarly the test source renders yellows, reds,<br />
blues,greens, or in-between hues compared to the reference. Values range from 0 to 100. Specific values may be used to supplement average values if one hue type<br />
is of particular concern. These scores are analogous to the special indices of the CRI system (e.g., R9), but are more robust because they combine several samples<br />
with different spectral features.<br />
