Water quality significantly impacts underwater color visibility through several factors:
- Turbidity: Suspended particles scatter light and reduce visibility
- Dissolved organic matter: Creates a yellow or brown tint
- Algae content: 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 phytoplankton and dissolved particles. Water quality can vary seasonally and with depth, affecting how colors appear at different times and locations.
