Just to further confuse the issue, I believe there is data which
suggests that at lower brightnesses (e.g., museum lighting levels)
the rods come back into play and shift our color perceptions.
All the standard colorimetry pretty much assumes that only the cones
are in play - which is indeed the case under the conditions in which
they gathered the standard observer data, but may not be fully
accurate in dimmer viewing rooms.
I believe some museums have discovered that D50 looks very "cold"
rather than neutral under low lighting levels, and have shifted to
"warmer" lights (3400K, etc.) to achieve the neutral appearance
associated with D50 at higher illumination levels.
Very very complicated our eyes...
