What colors should be avoided when diving with sharks?

Diving with sharks is an exhilarating experience that requires careful planning, including the consideration of what colors to wear. To minimize the risk of unwanted attention from sharks, it’s advisable to avoid bright and contrasting colors, often referred to as "yum yum yellow" or "bait colors," which can attract these curious predators.

Why Do Colors Matter When Diving with Sharks?

Sharks are known for their excellent vision, which is adapted to detect contrast and movement in the water. Bright colors like yellow, white, and neon hues can stand out against the natural ocean backdrop, potentially drawing sharks closer out of curiosity. While sharks do not necessarily associate these colors with food, they are more likely to investigate objects that are visually distinct.

What Colors Should You Avoid?

1. Bright Yellow: Often called "yum yum yellow," this color is especially visible underwater and can attract sharks.
2. White: This color contrasts sharply with the ocean environment, making it noticeable to sharks.
3. Neon Colors: Any fluorescent or neon attire can catch a shark’s eye due to its high visibility.
4. High Contrast Patterns: Avoid wearing gear with bold patterns or stripes that create a stark contrast.

What Colors Are Safer to Wear?

• Dark Blue or Black: These colors blend well with the underwater environment, reducing visibility to sharks.
• Dull Gray: This can help you mimic the natural hues of the ocean.
• Camouflage Patterns: Some divers opt for wetsuits with camouflage designs to further blend into the surroundings.

How Does Shark Vision Work?

Sharks have a unique visual system that is highly sensitive to light and contrast rather than color. Their eyes contain more rod cells, which are better for detecting movement and contrast in low-light conditions, typical of underwater environments. This makes them more attuned to differences in brightness rather than specific colors.

Tips for Safe Diving with Sharks

• Stay Calm: Sudden movements can attract sharks, so maintain a slow and steady pace.
• Avoid Splashing: Excessive splashing can mimic the actions of prey, drawing attention.
• Dive in Groups: Sharks are less likely to approach a group of divers.
• Follow Local Guidelines: Adhere to any specific advice or rules provided by local dive operators.

What to Do If a Shark Approaches?

If a shark begins to approach, remain calm and avoid direct eye contact. Slowly position yourself to face the shark without making sudden movements. If necessary, use your equipment to gently push the shark away, maintaining a respectful distance.
