There is evidence to suggest that certain colors of visible light do not reach the ocean floor or are significantly absorbed as the depth increases. Here are a few key points:

1. Light Absorption: As light travels through water, it gets absorbed by various substances present in the water, such as dissolved organic matter, phytoplankton, and suspended particles. These substances can scatter, reflect, or absorb different wavelengths of light. The deeper the water, the more light is attenuated or absorbed.

2. Depth-dependent Loss of Colors: The absorption of light in water is wavelength-dependent, meaning that different colors of light are absorbed to different extents. In general, shorter wavelengths (blue and green) are absorbed more rapidly than longer wavelengths (red and yellow). This phenomenon is known as selective absorption.

3. Loss of Red Light: Red light has the longest wavelength among visible light, and it gets absorbed relatively quickly in ocean water. In fact, red light is absorbed within the first few meters of the surface, meaning that it does not reach the ocean floor in any significant amount. This loss of red light explains why the color red appears dull or black underwater.

4. Dominance of Blue and Green: Due to the selective absorption of shorter wavelengths, blue and green light can penetrate the water column more effectively than red light, resulting in these colors dominating the underwater environment. It is worth noting that the exact penetration depth of different colors varies depending on factors such as water clarity, location, and time of day.

5. Lack of Color Perception: The absence of red light at greater depths reduces the ability of organisms to perceive colors accurately. As a result, underwater scenes appear bluish or greenish, as these colors are more prevalent.

Overall, the evidence shows that the color spectrum of visible light is significantly altered and attenuated as it passes through water, making certain colors, particularly red, virtually absent from the ocean floor.
