Lunar Surface Coloration

The moon is invariably characterized as a colorless object whose features fall into one of the countless shades of black and white. Nevertheless, there are reports from Apollo mission astronauts as well as ground-based observers of color being noted, thus reinforcing the rich and geologically diverse nature of the lunar surface.

The image below is a beautiful rendition of Mare Imbrium (Sea of Showers), the most dominant mare in the northern lunar hemisphere, whose diameter of 1250 kilometers and area of approximately 830,000 sq meters make it the second largest mare on the moon. It is believed to have been formed between 3.80 and 3.85 billion years and is characterized with a very flat and smooth floor with some wringling on the periphery. As clearly indicated by the image below, the upper portion is characterized with a light brownish tint whereas the remaining 70% or so is characterized with a much darker bluish tint.
