What Color Swimsuit Is Easiest To See Underwater?

Last update: 2023-12-06

Picking out a swimsuit can be a daunting task. With so many styles, patterns, and colors to choose from, it can be hard to know which one will be the best option for your needs. One important factor to consider is which color swimsuit will be easiest to see underwater. After all, you want to make sure you remain visible while swimming or doing water activities. So what swimsuit color provides the highest visibility underwater? Let's take a closer look.

Factors That Impact Underwater Visibility

When choosing a swimsuit for optimal underwater visibility, there are a few key factors to consider:

Light Conditions

The lighting conditions you'll be swimming in impact visibility. Indoor pools tend to have brighter, more direct light compared to open water environments. Outdoors, visibility is impacted by time of day, cloud cover, and water clarity. Early morning and late afternoon tend to have lower visibility than mid-day when sunlight is more direct.

Water Clarity

Visibility is directly related to how clear or turbid the water is. Clear tropical waters will allow better visibility than murky lakes or oceans. Chlorinated pool water clarity can vary too.


The deeper you swim, the more water light has to travel through which reduces visibility. Even the best swimsuit colors will become less vibrant at depth.

Swimsuit Color and Pattern

Obviously the color and pattern of your swimsuit itself will impact its underwater visibility. Dark or busy patterns are harder to see than bright simple colors.

Best Swimsuit Colors for Underwater Visibility

Taking all these factors into account, the following swimsuit colors tend to provide the highest visibility underwater:

Bright Primary Colors

Vivid primary colors like red, yellow, and orange are your best bet for high visibility underwater. These warm bright hues reflect light and contrast strongly against water, making them easy to see under various conditions.

A bright red or yellow swimsuit will stand out even in poor visibility. Orange is especially visible, as it contrasts against both blue water and green algae. These primary colors also aren't absorbed as much by water compared to other colors on the spectrum.

Fluorescent Colors

For maximum visibility, choose a fluorescent colored swimsuit. These super-bright, sometimes neon shades glow and reflect ambient light extremely well. They provide the highest contrast and visibility underwater.

A fluorescent pink, orange, green or yellow swimsuit is your best choice for low light open water swims. These suits will be visible even at greater depth and distance. Fluorescent colors also hold up better over time compared to darker brights.


A white swimsuit is highly visible underwater, performing nearly as well as fluorescents. The bright white fabric strongly reflects light. A white suit or print contrasts well against surroundings.

White can look almost florescent underwater. It stands out nicely whether swimming in sunny conditions or deeper darker spots. Just be aware that white tends to become transparent when wet.

Avoid Dark Colors

Dark colored swimsuits like black, navy, or dark purple suffer from poor underwater visibility. As colors get darker, they absorb more light instead of reflecting it back. This makes them fade and disappear underwater.

While dark colors may look stylish, avoid wearing them when underwater visibility is important. Stick to bright shades instead.

Swimsuit Visibility Aids

If you prefer the style or slimming effect of a darker swimsuit, consider adding visibility aids:

  • Bright colored swim cap in neon or primary colors
  • Goggles with colored lenses or silicone strap
  • Bright silicone swim skins or sleeves
  • Ankle floats or socks in visible colors
  • Rashguard with fluorescent accents
  • Swim buoys attached to your suit

The most important thing is finding a swimsuit you feel comfortable and confident swimming in. Make sure it fits your activity needs and safety is a priority. A brightly colored swimsuit can provide that extra visibility during open water swimming, scuba diving, snorkeling, water polo, synchronized swimming, or any activity spent mostly underwater. Just avoid darker colors that can disappear from view when wet. Focus on brightly colored suits in neon, fluorescent, primary or light colors for best all-around underwater visibility.
