Details

The earliest paper I am aware of is by Nickerson, et. al. in 1941. After the big Munsell renotation in 1943, the name blocks were revised in 1955.

When the central colors were recomputed in Kelly (1958), they were called the "Central Colors", though the text makes it clear that most are truly centroids, which were computed from the centroid of an "elementary shape", which is a "sector of a right cylindrical annulus". For the "peripheral blocks" of high chroma, the centroids were "estimated graphically by plotting the MacAdam limits".

In Kelly (1965) these were called "centroid colors", and that is the name we will use here.
