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.
The dark color is consistent with the presence of mafic rocks, such as basalt. The albedo of a surface usually varies with the wavelength of light hitting it. Mars reflects little light at the blue end of the spectrum but much at red and higher wavelengths. This is why Mars has the familiar reddish-orange color to the naked eye.
Solis Lacus feature on Mars. Screenshot from Celestia. Solis Lacus / ˈ s ɒ l ɪ s ˈ l eɪ k ə s), (Latin, "lake of the sun") is a dark feature onIt was once called "Oculus" and is still commonly called "The Eye of Mars" because with the surrounding light area called Thaumasia it resembles the pupil of one.
Mars is often referred to as the "Red Planet" because of the rusty, reddish-orange sandscape blanketing the planet. That comes into sharp focus in our first color photo snapped by the Mars ...
Generating accurate true-color images from Mars' surface is surprisingly complicated. [21] To give but one aspect to consider, there is the Purkinje effect: the human eye's response to color depends on the level of ambient light; red objects appear to darken faster than blue objects as the level of illumination goes down. There is much ...

Mars is the fourth planet from the Sun.The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". [22] [23] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.
