How far does sunlight travel into the ocean — and just what happens to all those different wavelengths of color as you go deeper into the depths?

The American Museum of Natural History put together this chart showing exactly how far light — and the different wavelengths of color that make up the full spectrum of visible sunlight — can travel into the depths of the ocean.
