Quote:As for water, it needs light to change color, and so you cannot say that water changes color on its own.
Colour belongs to the wave of light. Without light there is no colour. Water has no property of colour, in fact nothing has a property of colour. Every material only looks differently colour-wise because of how they interact with light waves. As such, water like air will scatter blue light, fortifying our eye sensory to read mainly blue visuals.
