Description

My attempt at showing the color differences on our moon's surface. These subtle colors can be brought out easily with astronomy cameras and heavy saturation, but they cannot be seen with our naked eye due to the moon's extreme surface brightness.
The colors are controlled by variations in iron and titanium content. The most notable red to blue color change in the Mare regions is caused by titanium oxide.
