Very differently than a camera!
https://en.wikipedia.org/wiki/Chromatic_adaptation
From the superb Color Primer by Fred Bunting (still a must-have reference
decades after being written):
"Chromatic Adaptation
The term chromatic adaptation, sometimes known as color consistency, refers to
the remarkable ability of our visual system to adjust the white point for a
scene so that colors appear the same independent of the color temperature of
the illumination. The color of an object does not appear to change from indoor
fluorescent light to daylight. This is such a common visual experience that we
take it for granted.
Chromatic adaptation can be a significant issue for color matching in graphic
arts. The white point of a monitor and the white of a paper stock may be quite
different. Although taken individually, the eye will see each as white. Side by
side, the monitor’s white may look rather blue in comparison to the paper’s."
