Parameters of the Color Rendering Index

The first column corresponds to the test sample number.

The third column corresponds to the appearance of the test sample illuminated by the D65 illuminant.

The fourth column shows the color of the sample illuminated by the reference illuminant. This color is used to calculate the General Color Rendering Index and it changes according to the spectral data.

The fifth column shows the color of the sample illuminated by the present spectrum.

The final column gives the color rendering index of the sample.

Warning: The colors are displayed as an indicative way.

You can view Ra and Chromaticity Difference (DC) values defined by the CIE. Details about CIE can be found here.

Note: Ra value is followed by the illuminant reference name used to calculate Ra.

Note: Ra value is also displayed in the status bar of the Colorimetric data diagram. For more details, you can view Parameters of Chromaticity Coordinates Tool.
