Sharks are large creatures with impressive bodies and terrifying teeth, rarely encountered by humans. Although some people want to see sharks up close, most still feel scared by their fierce appearance. Sharks are often associated with fear, especially in movies and folklore. However, it has recently been discovered that there are certain colors that can repel sharks. This is good news for ocean swimmers.

Actually, sharks see the world in various shades of gray or dim. Sometimes, they can also see green and purple colors. The National Oceanic and Atmospheric Administration (NOAA) then recommends the use of dim colors, as bright colors can attract the attention of sharks. These terrifying sea creatures have evolved to hunt for food more effectively in murky waters. Therefore, black color becomes the right choice to use, ensuring that sharks will not be able to see it from a distance of 1 mile.

Beside blue, sometimes the water appears greener. Therefore, besides gray, sharks sometimes see green and purple colors in the water. Because green is a natural color found in water or marine plants, it can be a safe choice to use. Sharks may misinterpret that the green seen is only the color of marine plants.

Sharks, giant creatures in the ocean, tend to be insensitive to the gray color differences around them, so someone wearing gray clothing while swimming is more likely to go undetected by the shark.

Apart from grey, sharks also see the color white. This color can blend with water, making someone appear more hidden. However, sometimes the brightness of the white color can create problems. Some studies show that lemon sharks are more attracted to wet clothes that are yellow or white in color. Therefore, this white color is quite controversial in relation to sharks.
