Yes, I also would think there's a difference between judging a large area of
uniform color and the small areas (less than 2 degrees) of adjcent colors in an
image, where simultaneous contrast comes into effect, so 2 degrees would be
most appropriate for the latter.

How were the observations made, were they single colors or 2 or 4 different
colors adjacent to each other?
If they were single colors there would be no context and therefore would not be
a realisitic way of determining the experience of color.
I’m curious about the observer conclusions and what can honestly be said about
them. Whether from 10° or 2°, does the observer test have a some weaknesses -
maybe a lot of weakness?
It seems to me that the matter involves relying on “the best we have” even
though it isn’t the best it could be.
