Las Coloradas, a small fishing village on the eastern coast of Mexico’s Yucatan Peninsula, is famous for its stunning pink lakes. But Why Is Las Coloradas Pink? What makes the water in these lagoons shimmer with such a vibrant hue? The answer lies in a fascinating combination of natural elements.
The Science Behind the Pink
The pink color of Las Coloradas’ lakes is not an illusion or a trick of the light. It’s the result of a high concentration of microorganisms that thrive in the salty waters. These include:
- Dunaliella salina: This type of microalgae produces a reddish pigment called beta-carotene to protect itself from the intense sunlight.
- Halobacteria: These extremophile bacteria also produce pigments that range in color from pink to red and even purple, depending on their concentration.
As these organisms flourish in the shallow lagoons, their pigments become highly concentrated, giving the water its distinctive pink color.
Salt Production and Its Colorful Effect
Las Coloradas has a long history of salt production dating back to the Mayan civilization. The unique ecosystem of the lagoons, with their high salt content, made it an ideal location for salt harvesting. The process involved creating shallow ponds where seawater evaporates, leaving behind salt crystals. This process also contributes to the vibrant colors of the lakes. As the water evaporates, the salt concentration increases, creating an even more hospitable environment for the pigment-producing microorganisms.

Visiting Las Coloradas
Today, Las Coloradas is a popular tourist destination where visitors come to marvel at the pink lakes, learn about the salt production process, and witness the unique beauty of this natural phenomenon.
“The intensity of the pink can vary depending on the time of day and year,” explains Dr. Maria Sanchez, a marine biologist specializing in halophile organisms. “The angle of the sunlight and the concentration of salt and microorganisms all play a role in creating those stunning shades of pink.”
If you’re planning a trip to Las Coloradas, remember to:
- Protect yourself from the sun, as the reflection off the salt flats can be intense.
- Respect the fragile ecosystem by staying on designated paths and avoiding disturbing the water.
Las Coloradas offers a unique opportunity to witness the incredible power of nature and the beautiful interplay between salt, microorganisms, and sunlight. The pink lakes stand as a testament to the diversity and wonder of our planet’s ecosystems.
