James Gurney Color and light
Underwater caustics:
Caustic patterns can occur when sunlight is refracted downward by the ripples at the water surface. The waves focus a network of dancing lines on the sea floor or on the backs of creatures below the surface.
Underwater caustic effects don't occur much deeper than twenty or thirty feet.
it would be inaccurate to include them in a deep sea picture.
In addition, they only occur on sunny days and are visable only on the top surfaces of underwater forms.
So what is refraction? When a drinking glass or water filled vase are hit by sunlight, the object will bend also known as refract the light, essentially acting as an imperfect lense.
Gurney Imaginitive realism: painting a mermaid underwater,
Skintones appear cooler in water than they do in the air, and the sideplanes of the figure fall away to a bluish tone, lit from all directions by scattered light in the water.
Hope that helps in combination of looking at underwater pictures.
