What Does The Color Code On Coral Mean?

Have you ever tried to find the color code for coral? Sometimes it’s difficult to decipher what you’re looking at! But did you know that sometimes, a color can stand in for more than one meaning? In this article, we’ll go over how coral color codes work and why they were created.

The color code on coral can indicate the level of stress the coral is under. The higher the number, the more stressed the coral is. The most common codes are:
– Green: No stress.
– Yellow: Moderately stressed.
– Orange: Extremely stressed.
– Red: Dead or dying coral

What Does Coral Color Mean?

The color of coral can be a useful indicator of its health. Corals that are darker in color generally indicate a healthier environment with more nutrients and less pollution, while lighter colors may indicate a more polluted area. Coral also displays different colors based on the type of coral. For example, some corals are red or pink due to the presence of anthocyanins, which give the coral its color.

How to Determine Coral Colors

The color code on coral refers to how coral is classified. The three main categories of coral are soft corals, hard corals, and stony corals.

Soft corals are the most common type and comprise many small individual polyps. These polyps can be white, pink, yellow, light green, or dark green and range in size from a few millimeters to a few centimeters.

Hard corals are made up of fewer but larger polyps and can be either cream or black. They are usually more durable than soft corals and can live for many years with only minor repairs.

Stony corals are the rarest type and comprise large calcium carbonate plates forming a skeleton. They come in different colors: red, yellow, brown, gray, purple, and black.

What Myths Do People Believe About Coral Coloring?

The color code on coral can be a little confusing for some people. Coral experts say the three colors you see on coral are just shades of pink, yellow, and white.

The blue light that filters through the water and casts these colors onto coral is called “ultraviolet radiation.” Although many people believe that the different colors represent different types of Coral diseases, this is not true.

The color codes are simply used to help experts identify coral reefs when they’re looking at satellite images or maps.


Coral is a beautiful and delicate sea creature that can be found worldwide. The color code on coral means different things depending on where you are in the world. In the United States, it indicates that coral is safe to touch or collect because of its low levels of toxins. Elsewhere in the world, coral can be used as traditional medicine. So if you’re ever out diving and come across some coral with this color coding, don’t be afraid to take some pics and post them on social media for everyone to see!
