Mars surface color

Yogi Rock, analyzed by the *Sojourner* rover (July 4, 1997)

The surface color of the planet Mars appears reddish from a distance because of rusty atmospheric dust.^[1] From close up, it looks more of a butterscotch,^[1] and other common surface colors include golden, brown, tan, and greenish, depending on minerals.^[1]

The apparent colour of the Martian surface enabled humans to distinguish it from other planets early in human history and motivated them to weave fables of war in association with Mars. One of its earliest recorded names, Har decher, literally meant "Red One" in Egyptian.^[2] Its color may have also contributed to a malignant association in Indian astrology, as it was given the names Angaraka and Lohitanga, both reflecting the distinctively red color of Mars as seen by the naked eye.^[2]
