The following table shows the chromaticities computed from the Macbeth colour checker spectral reflectance curves. Also given are the RGB values computed according to the XYZ to RGB matrix and normalization required for the fourth assignment. The RGB values have been clamped to the 0 to 1 range and gamma corrected with a 2.0 gamma curve. The colour swatches show the final computed RGB colours.
