Lets find out what and why sharks are attracted to colors.
Why Sharks Are Attracted to Certain Colors
Sharks are attracted to certain colors due to their unique visual perception and hunting strategies. Their eyes are adapted to detect contrast and motion, which play crucial roles in their ability to locate prey in diverse marine environments. Here’s why specific colors can attract sharks:
High Contrast:

Sharks have excellent contrast sensitivity, meaning they can easily detect objects that stand out against the background of the water. Colors like yellow, white, and black create strong contrasts, making them more noticeable to sharks.
Light Reflectivity:
Colors that reflect a lot of light, such as silver and white, mimic the appearance of fish scales glinting in the water. This can attract sharks as it resembles the natural appearance of their prey.
Environmental Adaptation:
Sharks’ vision is adapted to the ocean’s lighting conditions. In murky or dim water, bright and reflective colors are more visible. This heightened visibility makes it easier for sharks to detect potential food sources.
Specific Colors and Their Effects
Yellow:
Often referred to as “yum-yum yellow,” this color is highly visible underwater. Its brightness contrasts sharply with the blue and green hues of the ocean, making it an easy target for sharks’ keen eyesight.
White:
White objects create a stark contrast in the water, especially in darker or deeper environments. This contrast can attract sharks by standing out against the surrounding water.
Silver:
Shiny, reflective surfaces can attract sharks as they mimic the natural light reflections from fish scales. This glinting effect can draw sharks’ attention, as it suggests the presence of fish.
Black:
Dark objects can also stand out, particularly against lighter backgrounds or in clear water. The strong contrast between black and other colors can make black objects more noticeable to sharks.
Less Attractive Colors

Colors that blend in with the ocean environment, such as darker blues and greens, tend to be less attractive to sharks. These colors do not create as strong a contrast against the water, making them less noticeable to the sharks’ eyes.
Understanding the visual perception of sharks helps explain why certain colors attract them more than others. When in shark-prone waters, it’s advisable to avoid wearing high-contrast or reflective colors to minimize the risk of attracting these predators.
