Venera 13 images of the surface of Venus

The rocks on Venus are a dull gray, but sunlight filtered by the thick atmosphere gives them a yellow tint. This Venera 13 color photo shows plates of rock thought to be basalt, with dark soil between some of them. The lower photo has been corrected to show the color of the surface as it would appear under direct sunlight. This site is probably typical of the plains on Venus.
