[QUOTE="Kodiak, post: 179166, member: 15426"] •[COLOR="#FFFFFF"]••[/COLOR] [COLOR="#B22222"] Kodiak, [B]your tip about the WB on the first pic worked great to get rid of the bluish tint.[/B][/COLOR] No tip! … just common sense (maybe that's the tip!)… Ok, let's go: 1. The Moon, seen from outside the atmosphere, has a colour composite of 320 nm light [COLOR="#FFFFFF"]•••[/COLOR]in blue, 415 nm in green and 689 nm in red. [INDENT][B]NASA • Lunar Reconnaissance Orbiter: [/B] 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.[/INDENT] 2.
