It seems X-Rite and Munsell or PANTONE no longer sells ColorChecker charts
anymore? It looks like they gave the business away to a company called
“Calibrite”, which may be an X-Rite subsidiary?
I had to buy a fresh Munsell ColorChecker chart, recently, the 24 patches
version, but I was surprised that the “packaging” (the envelope) no longer
contains the original Illuminant C xyY values and their Munsell notations?
What a pity… They use to print this information on the package itself ☹
