Dovid and Sara Go To the Moon - where do the lunar colorful strips and blotches of color come from

Intrigued by the colorful patterns occasionally visible on the Moon’s surface, Dovid, Sara, and their trusty robot Rocky set out to learn more. They found that transient lunar phenomena (TLP) were first observed over 1,500 years ago, yet their cause and underlying science remain a mystery. After some careful thought, the trio decides to travel to the Moon themselves, hoping that witnessing these events firsthand might help unravel some of its many secrets. Watch as they secure a ship to carry them to the Moon, prepare the food and supplies they’ll need, and make sure Rocky, their robot, is ready for the journey through space. See Rocky repair the lunar rover left behind by Apollo 17, allowing them to roam the Moon with ease and reach the perfect spots for witnessing a TLP up close. Transient lunar phenomena (TLPs) are described as short-lived changes in the brightness of patches on the face of the Moon. They last anywhere from a few seconds to a few hours and can grow from less than a few to a hundred kilometers in size. Most instances of TLPs are described as increases in the overall luminosity of a spot on the Moon; however, sometimes observers report a decrease in a region's brightness or even a change in its color to red or violet. Hundreds of amateur and professional astronomers have documented their observations of TLPs since the invention of the telescope. A number have been confirmed by multiple observers or even photographed. A few TLPs were even reported by Apollo astronauts as they orbited the Moon
