Taken on 29th Sept 2023, I have increased the colour saturation of this Moon image to reveal areas that are rich in Iron and Titanium.
Canon EOS R7, 1/200 sec ISO100 F8, 30 frames processed in Autostakkert!3, Wavesharp and PS CC.

Colors on the Moon are dominantly controlled by variations in iron and titanium content. The mare regions have low reflectance because they contain relatively high amounts of iron oxide (FeO). Some mare basalts contain unusually high amounts of titanium oxide (TiO2) in addition to iron oxide, making for even lower reflectance. TiO2 also shifts the color of the mare from red to blue.
