Water quality significantly impacts how we perceive colors underwater through several factors:
- Turbidity: Suspended particles scatter light and reduce visibility
- Dissolved organic matter: Creates a yellow or brown tint
- Algae presence: Can create green or red color casts
- Salinity: Affects light refraction and clarity
Clear ocean water appears blue because it absorbs red light while scattering blue light. However, coastal waters often appear greener due to higher concentrations of plankton and organic matter. In extremely clear water, like tropical seas, colors remain truer to their surface appearance at greater depths compared to murky or polluted waters.
