Actually water absorbs red and orange light the most and then yellow, purple and green, and absorbs little blue and cyan. So it always shows blue bluish under the deep water. In addition, the color cast becomes greater when light spread longer and deeper.

We always correct the color by the following ways.

1. Shorter the distance during photography.
2. Use led to fill light during underwater photography. Use the orange filters when light is under 2500k and red filters when above 2500k.
3.Use the color correction filter.
