Default Do leaves change their colour according to the brightness ?

I´m trying to understand why we perceive colours in nature different
in dependency on the intensity of the illumination. According to this
I read that the chlorophyll cells in leaves can change their position
away from the center to the periphery if the illumination is very
bright. Can anybody tell me if this really the case as, say a kind of
protection mechanism against "overexposure", and if it can lead to a
different colour impression ?
