Thanks Guys!
For those who are interested in the colour saturation process, here are a couple of useful links:

From Zac’s website:
"The colours arise from compositional differences in the Moons rocks. In general, blue indicates Titanium-rich rock while red indicates titanium-poor rock. However other processes, including maturation of the regolith by micrometeorites can also cause reddening (such as in the highlands which are generally older than the mare)."
