Actually, a red apple in a red room in red light will look white.....try
it.
when changing the Illumination the perceptual system both cogentive and
sensory mechanisms try to make us perceive the same colour. i repeat and
emphesise the word try. which means our perceptual system is not always
capable of retaining the same colour perception when the illumination
changes. especially when the change in the illumination is dramatic like the
example you are giving. but if you look at a gray paper under D50 und D65 it
will look in both cases gray. which means the visual system is capable in
this of changing it4s sensitivity so that the Hue does not change.
