First Color Disappear When Diving

What Is The First Color Disappear When Diving?


Red is the first color to go when you dive underwater, and it’s not because it’s bright or flashy. It’s because it absorbs all the other colors around it. This makes it hard for humans to see anything else in the water once submerged. In this article, you learn about First Color Disappear When Diving Flip Backward in water.

When underwater, your eyes are surrounded by a layer of water in front of them. That water is clear and reflects light in all directions except for the red wavelengths that make up red light. 


This means that if there’s a lot of red light around, it will be reflected right back at you, making it harder for your eye to see anything.

And if you’re looking through a clear tube into an aquarium full of brightly-colored fish, those colors will also bounce off the walls and become confused with the background, which can cause them to disappear from view entirely.


Reasons for first colour loss when underwater are listed below.

Causes Of The First Color Disappear When Diving

When it comes to diving several factors can contribute to the first color Disappear when diving:

1- Blood Pressure

The primary cause of this first color loss is high blood pressure. Sodium retention in the body is the root cause of hypertension. The standard amount of salt in your blood is about 140mg/dL, but if you have high blood pressure, this number will be higher than it should be.

When your body loses its first color, it is released from the adverse effects of high salt levels, which reduces swelling. This helps with pain levels, making life feel more pleasant after you’ve come up from the water.

2- Water Absorbs a Certain Wavelength

The first color to disappear when diving is red. In particular, water absorbs the blue and green light that the human eye is most susceptible to.

The first color disappear when diving is caused by the absorption of water in the eyes, which causes excess tear production. The water removes the tear film that protects the eye from environmental damage, causing the first color to disappear.

The loss of vision can be temporary or permanent, depending on how long you have been underwater and if you have any underlying health conditions. If it is temporary, you may notice some vision problems, such as blurry vision or temporary blindness after being underwater for a while.

3- Eye Sensitivity 

The first color disappear when diving is the color red. This is because there is less oxygen in the atmosphere at greater depths, so the body’s ability to absorb it is reduced.

As you descend, your eyes are exposed to more intense light than they are used to. The increased sensitivity and difficulty in adjusting is a result of this. 

The other factor contributing to this decrease in eye sensitivity is that as we descend, our blood pools into our legs, diluting them and reducing their ability to carry oxygen around our bodies efficiently.


As we descend deeper, our eyes become less sensitive and unable to adapt or compensate for this change in conditions.

The most common reason for losing the first color of light is that we need to adjust our eyes’ sensitivity to compensate for the increased pressure in our bodies. 

4- Light Scattering

Light scattering is a phenomenon that can cause the color of light to change as a diver descends.

Light scattering is caused by particles in the air and water, which act as diffraction grating, scattering light waves. As these particles move through the water or air, they change the light’s wavelength. 

This causes the color of light to change from blue to red. The amount of scattered light depends on how much water or air is in each location.

This happens because light travels in waves, so when you are underwater and not moving your eyes or body around, the water will absorb some of the light. This causes a change in how much light reaches your eyes and brain.

5- Light Diffusion Through Water

Sometimes, when you dive, the first color you lose is red. This is because of the diffusion of light through water.

The reason for this is that light travels in waves. When underwater, the waves are smaller than they are on land, so the intensity of light that passes through your body will be diminished. In addition, there are other factors:

  • The pressure in your lungs decreases as you go deeper; less oxygen reaches your bloodstream.
  • Your blood oxygen level decreases as you go deeper; less blood is available to carry nutrients to your tissues.
  • This means that all these things work together to cause a loss of blue in your vision as you dive deeper into the water.


In the end as we have already mentioned, red is the first color disappear when diving. As you descend into deeper waters, red light is absorbed more quickly than other colors. Then this color will disappear from your vision.

If the water is murky or contains a lot of suspended particles, it will absorb more light than clear water would and therefore cause colors to be disappear sooner.

Additionally, make sure to use high-quality equipment when diving. Poorly maintained gear can lead to decreased visibility underwater and a lack of vibrant colors for your dives. 

Ensure all your equipment is properly cared for and maintained so you can enjoy colorful dives all year round.


What Color is the First to Disappear When Diving?

Generally speaking, red is usually the first color to disappear when diving. This is because red light has a longer wavelength than other colors, meaning it doesn’t penetrate as far into the water. 

As you dive deeper, other colors, such as orange, yellow, and green, will also start to fade away.

Are There Ways to Preserve Color When Diving?

Yes! One way to preserve color when diving is to use a filter or mask explicitly designed for underwater use. These filters reduce the amount of light filtered out, allowing you to see more vibrant colors at greater depths. 

Additionally, wearing polarized sunglasses can help reduce glare and increase diving visibility. Finally, a dive light can also help bring out more colors in deeper dives.

What are Some Tips for Maintaining Underwater Vision?

When diving, it’s essential to maintain good underwater vision by protecting your eyes from hazards such as debris or stinging jellyfish. 

To do this, wear goggles or a full-face mask with tempered glass lenses that offer UV protection and an anti-fog coating. 

Additionally, use earplugs to protect your eardrums from any potential pressure changes. Last but not least, protect your eyes from drying up by drinking enough of water throughout your dive.
