At first glance, the moon looks simple, like a silvery-white body in space. But, if you look closer, there’s more to see. The moon doesn’t make its own light; it reflects the sun’s light. Its surface is mostly grey, like old asphalt, but it can change color for many reasons. So, what are the colors of the moon?
The moon’s color can shift based on the rocks on its surface and the Earth’s atmosphere. Depending on where the moon is in the sky and the air around us, it can look red, orange, yellow, or even blue. Learning about what changes the moon’s color helps us appreciate the complex dance of light, rocks, and air around us.

Moon’s Surface Composition
What are the colors of the moon? The answer lies in the diverse geology of its surface. Dark, iron-rich mare basalts and lighter-colored anorthosites create a varied palette, revealing the moon’s dynamic past.
Mare Basalts
Mare basalts, or lunar basalts, cover about 16% of the moon’s surface. These dark, volcanic rocks came from the moon’s interior melting. This led to the eruption of iron-rich lava that formed the maria, or “seas,” we see now.
Breccias
Rocks known as breccias are composites of meteorite impacts. They can be light to dark grey. This shows the varied origins of their parts.
Anorthosites
The highlands are mostly anorthosites, a light-colored rock with mostly plagioclase feldspar. These ancient rocks tell us about the moon’s early days and how it changed.
Regolith
A layer of regolith covers the moon’s solid rocks. It’s a loose, fragmented material in shades from light grey to almost black. This regolith came from years of meteorite impacts and rock breakdown.
These rocks and the moon’s minerals make its surface colorful and textured. They give us a peek into the moon’s complex geological history.
The “Man in the Moon”
The moon’s dark spots, or “mare,” form shapes that look like a face. This is known as the “Man in the Moon.” It happens because our brains like to see patterns and shapes in random things. These dark spots are from old volcanoes and are made of mare basalts, contributing to what are the colors of the moon.
This idea of the “Man in the Moon” is found in many cultures. In Norse mythology, Máni is the male personification of the Moon who crosses the sky in a horse-drawn carriage. In Chinese mythology, the goddess Chang’e has a Moon rabbit with her. Greek mythology links it to a man carrying a heavy load and sometimes a small dog.
Looking for the “Man in the Moon” is less common near the South Pole. This is because the moon always shows the same side to Earth, thanks to its orbit. Western art often shows a simple face or a human profile in the moon, but it doesn’t match any real marks.
The “Man in the Moon” is seen as a mythical figure, not tied to the moon’s marks. These dark spots, called maria, were once thought to be oceans. But they’re actually made of basalt from old lava flows, impacting what are the colors of the moon.
The “Man in the Moon” is part of many cultures, like Vietnamese, Japanese, Haida, and Latvian traditions. In the Northern Hemisphere, everyone sees a smiling snowman-like face in the full moon. This has led to many legends over time.
The “Man in the Moon” is a fascinating part of our moon. It has captured the world’s imagination for centuries, showing its lasting appeal.
Shades of Gray
The moon’s surface looks gray at first glance, but it’s actually full of subtle color changes. These changes come from the different types of rocks on the moon, contributing to what are the colors of the moon.
The dark areas, called mare basalts, are made of black volcanic rock. This happened about 3 billion years ago, when lava flows covered the moon. The lighter areas, or highlands, are mostly ancient rock called anorthosite.
There are also breccia rocks on the moon, made from meteorite impacts. These rocks can be light or dark gray, depending on what minerals they have.
The moon has a dusty layer called regolith, made from meteorite impacts over billions of years. This layer is dark gray and makes the moon look gray overall.
Even though the moon seems mostly gray, it has many different rocks, affecting what are the colors of the moon. From dark basalts to light anorthosites, the moon’s surface is complex and colorful. This shows its rich history.
The moon’s gray colors tell us a lot about its makeup and how it was made. By looking at the colors and rock types, scientists can learn about the moon’s past. This helps us understand the moon’s history and the processes that shaped it.
The Red Moon
The moon can look red or orange, especially when it’s near the horizon. This color comes from how the moon’s light interacts with Earth’s atmosphere. The atmosphere scatters shorter light waves, letting longer, redder waves reach our eyes.
When the air is full of particles like dust from volcanoes or storms, the moon can look even more red. This red color is sometimes called a “blood moon” or “red moon.”
Lunar Eclipses
During a total lunar eclipse, the moon can look reddish or copper-like. This happens when the Earth blocks the sun’s light from reaching the moon. The light that does reach the moon has traveled through Earth’s atmosphere, making it look red or orange.
- Usually, only about one in three lunar eclipses are total.
- About four to five total lunar eclipses can be seen from any single location on Earth in a decade.
- The years between 1582 and 1908 did not have any lunar tetrads (a series of four consecutive total lunar eclipses).
- The next 250 years—from 1909 to 2156—will have 17 lunar tetrads.
- The current century—2001 to 2100—will have eight lunar tetrads.
Atmospheric Scattering
The red or orange color of the moon during a total lunar eclipse is due to Rayleigh scattering, contributing to what are the colors of the moon. Sunlight has different colors, and the longer wavelengths (red and orange) pass through the atmosphere better than the shorter ones (blue and violet).
This is why the moon looks red or orange. The exact shade of red or orange can change with the air’s conditions, like dust levels. Scientists use the Danjon Scale to measure the moon’s color and brightness during eclipses.
The Yellow Moon
This makes it look yellow. The scattering of light in the air makes the moon yellow. Blue light gets scattered more, leaving yellow and red to reach our eyes. This is why sunsets look orange or red too.
The yellow moon is not as striking as the red moon during a lunar eclipse, another example of what are the colors of the moon. But, it’s more common when the moon is low in the sky. Its soft light can make the landscape look warm and inviting.
The yellow moon has meant a lot to many cultures over time. In Egyptian myths, it’s linked to the god Thoth, who represents wisdom and magic. In Chinese stories, it’s where the elixir of life lives, meaning immortality. The yellow moon affects us more than just how it looks.
Astrology says it can show us our feelings, what drives us, and how we can grow. Thanks to new technology, we can now see the yellow moon and its details more clearly. Photographers use special techniques to capture its colors and textures beautifully.
The Blue Moon
The moon often looks gray, but sometimes it appears blue. This is called a “blue moon.” It happens when the moon’s light passes through dust in the air.
This dust scatters the red light more than the blue light. So, the moon looks blue. A famous blue moon was seen in 1950 after a big forest fire in Canada.
Atmospheric Particles
A blue moon needs the right size of dust in the air. The dust must be wider than red light and not too big or too small. This mix makes the moon look blue.
“Once in a Blue Moon”
A “Blue Moon” also means two full moons in one month. This is rare, happening every 2 or 3 years. In 2018, there were two blue moons close together, a rare event.
The next blue moon is on May 31, 2026. The last one was on August 31, 2023, and it was a supermoon. The name “blue moon” might come from an old word meaning ‘to betray.’ It could mean the moon’s unusual appearance.
Blue moons are rare and special events, contributing to the mystery of what are the colors of the moon. They don’t really make the moon blue, but the term has stuck with us. It means something very rare happens “once in a blue moon.”
Capturing the Moon’s Colors
Skilled astrophotographers have found ways to show the moon’s hidden colors. They use HDR (High Dynamic Range) photography and algorithmic processing. This reveals the moon’s subtle hues and tones, showing its geological features and composition.
Nicolas Lefaudeux is one such photographer. He made a special algorithm to bring out the moon’s color details. By understanding how light interacts with the lunar surface, he creates stunning images. These images show the moon’s true beauty and diversity.
HDR Photography
For better color in moon photography, shooting raw is best. Adjusting the color temperature can improve moon images. Increasing saturation and vibrance makes colors richer, especially with low ISO settings.
Exporting files as TIFF format keeps the 16-bits of color depth. This allows for more detailed color representation.
Algorithmic Processing
This fine-tunes the color enhancement, bringing out subtle hues and tones. Marcella Pace, an Italian teacher, has made a stunning composite image over 10 years.
NASA and the Astronomy Photographer of the Year Awards have recognized her work. It shows the beauty of the moon’s colors. Pace’s work is not just beautiful. It shows respect for all life. By revealing the moon’s hidden colors, she invites us to see the lunar landscape in a new way.
White Lunar Craters
The moon looks mostly grey, but it has some white spots you can see with your eyes. These are big impact craters like Tycho, Aristarchus, and Copernicus. They have white rays and ejecta that spread out for thousands of miles.
The exposed rock and minerals that the impacts pushed up are what cause these white spots. They stand out against the moon’s grey surface. The lunar craters and white features show us the moon’s impact sites and geology.
The Wood’s Spot near the Aristarchus and Herodotus craters looks like a mustard-colored area. The Lassell Massif has tan colors, and the Ina crater in the Lacus Felicitatis is light-blue.
Apollo 17 astronauts saw orange-ish and dirty brick-red spots near the Montes Haemus, contributing to the question of what are the colors of the moon.
They also saw two reddish-brown-colored ray craters in the Bowen-Sulpicius Gallus area, further adding to the mystery of what are the colors of the moon. The Langrenus and Beaumont L craters had orange or reddish spots on their slopes and floors.
These white features and color variations show the moon’s complex geology and impact history. They give us a peek into how the moon formed and changed over time.
What Are the Colors of the Moon?
The moon’s color is not just one color. It can look like grey, but it can also appear in shades of yellow, orange, red, and even blue. This depends on many factors affecting color.
What rocks and minerals are on the moon, where it is in the sky, and our atmosphere all affect its color. We see red hues during a total lunar eclipse and blue tones with special cameras. These colors show how light, geology, and atmosphere work together to change how we see the moon.
The moon color changes a lot because of different factors affecting color. For example, its grey look comes from the rocks and minerals on its surface. These include things like magnesium, iron, and feldspar, which make a fine, grey dust.
But sometimes, the moon looks yellow or orange. This happens during the Harvest Moon, when its light goes through more of our atmosphere. This scatters the blue light, making the moon look warmer.
During a total lunar eclipse, the moon can look reddish-orange. This is called a “blood moon.” It happens because our atmosphere blocks the blue light, letting the red light reach the moon.
The moon’s color changes often and is very interesting. It shows how the moon, our atmosphere, and its geology work together.
Exploring Lunar Geology
The moon’s surface is a fascinating mix of different landscapes, shaped over billions of years, contributing to the intriguing question of what are the colors of the moon. Dark, iron-rich mare basalts fill the large, flat plains.
On the other hand, the lighter-colored anorthosites of the lunar highlands stand out. Each type of rock plays a role in the moon’s unique look.
Impacts from meteorites create breccias, and the moon’s surface also has a layer of loose, broken-up material called regolith. These elements make the moon’s surface complex.
Anorthosite, a white rock rich in calcium, is thought to be part of the moon’s ancient crust. It’s made mostly of plagioclase feldspar. This rock is bright and covers much of the moon’s surface. In contrast, the mare basalts are dark and rich in iron and magnesium. They form many of the moon’s dark areas.
The lunar highlands are light-colored because they are poor in iron but rich in calcium. The regolith, or moon soil, is a blend of different-sized particles. It includes fragments from various rocks and glass from meteoroid impacts.
Learning about the moon’s geology helps us understand how it formed and changed over time. It also explains the moon’s colors and features we see in the night sky.
Over 200 new impact craters were found on the moon in just the first 7 years of the Lunar Reconnaissance Orbiter mission. Floor-fractured craters have shallow floors with many fractures, showing the moon is still active. The Apollo Program brought back over 800 pounds of moon rock and soil for study. This helped us learn more about the moon’s past.
Exploring the moon’s geology shows us the amazing diversity of its rock formations and ongoing processes. It gives us a glimpse into the moon’s history and evolution.
Conclusion
The colors of the Moon are not simple, and the question of what are the colors of the moon is more complex than it seems. The surface looks mostly grey but changes a lot. This depends on the minerals, rocks, the Moon’s position, and Earth’s atmosphere. The Moon can look red during a total lunar eclipse or show blue in rare photos taken by experts.
