Why is the Color Red Especially Used Inside Submarines?

Submarines have been one of the main tools for humanity's underwater explorations that have excited us in recent years. Starting in the 19th century, they are still in use today.

Why do submarines use red light inside? There is a logical reason!

The underwater world has a very different atmosphere than we imagine.

Red lights play an important role in marine science and offshore energy. There are very necessary reasons for using the full red color inside submarines.

The longer wavelength of red light allows it to penetrate water better than other colors. This improves visibility in murky or deep water. For marine scientists, red LEDs allow for clearer observations where white light scatters and distorts images.

Red light is less obtrusive.

Red light is also preferred because it does not affect the crew's biological clock and facilitates eye adaptation. The fact that red light, unlike other colors, does not affect the circadian rhythm, which covers all behaviors within 24 hours, is of great importance in submarine operations.

In addition, the eyes adapt more easily to red light, making it more comfortable to work in dark environments. This feature allows the submarine crew to read screens and panels more easily while spending long hours underwater.

This type of lighting is also common in airport control towers or in theaters and movie theaters.

Red light allows the eyes to better adapt to the night environment, improves performance and maximizes comfort. And these are the biggest reasons for its use.
