Different colours of light also travel at different speeds

Different colours of light also travel at different speeds, and water slows light down. So as you dive down into the water, the first colour to be filtered out by the water is the slowest: red.

That means that at 30 feet or so, there is no red light in the water, so red light can’t bounce off blood into our eyes. Instead, green is reflected by green pigments in the blood that are usually hidden by the reflected red light. If you went even deeper, the blood would change from green to black.💉💉
