Color-enhanced Moon Mosaic

   We usually see the moon as a monochromatic planet only with releif and dark/bright surface details. But we can enhance low color contrast to reveal details, hidden from naked eye. Color hues still real on this image, while saturation was significantly strengthened. (Post-processing of such images is quite similar to hue/saturation adjusting tools in  image editors, but have some specificity)

   Color features represent real geological differences of regolith regolith compound. As example - bluish regions are rich of titanium, brown have vulcanic origin, orange are metal-poor regions etc.
