Fraidy is both scientist and
philosopher.
Firstly, materials have a net
property that causes them to reflect light of a specific
wavelength or multiple wavelengths in specific combinations.
Some materials change
reflective properties as their temperatures change. If their
reflective properties do not change enough, they will always
be the same color in visible light.
In the dark, materials will
not change their reflectivity characters unless something
else in their make up changes. One aspect that may change is
temperature.
In the dark materials tend to
cool. Therefore, in the dark some materials will change
their reflective properties.
If those materials were to
suddenly be lighted, they may warm slowly and therefore
change color. If a given material were lighted but not
enough to cause warming, it would remain a consistent color.
What other properties might
change in the dark and potentially cause a color shift? |
