Do the tiles in the Farnsworth Munsell 100 Hue test kit require calibration? If so, what can change that would require their recalibration? If they require calibration, what is the frequency?

To my knowledge, and in my experience with our F-M 100 Hue tests, they are very stable with respect to color change. Our very old tests appear to provide results consistent with out new tests. (That said, note that the manufacturer of these tests, GretagMacbeth, certifies the caps for a period of two years.) The color chips could fade over several years if left exposed to light, but that would be rare for F-M 100-Hue chips since they come in boxes, and should be stored there when not in use.

More likely of concern than fading of the colors would be simple wear and tear damage from the handling of the chips. Sometimes they get dirty or damaged by finger prints. When such damage becomes noticeable, it is likely time to get a new test.

The tests, and more information on their stability, are available commercially from GretagMacbeth. They produce and sell all Munsell products and are not associated with our laboratory (we're just named after the same person). More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
