The surface of the planet Mars appears reddish from a distance because of rusty dust suspended in the atmosphere.
The latter refers to the effect of the iron oxide prevalent on Mars' surface, which gives it a reddish appearance distinctive among the astronomical bodies visible to the naked eye.

Iron

FeFe 2+ Fe(III)
The rest of the iron in the dust, perhaps as much as 50% of the mass, may be in titanium enriched magnetite (Fe 3 O 4 ).
The proverbial red color of the surface of Mars is derived from an iron oxide-rich regolith.

From closeup, it looks more of a butterscotch, and other common surface colors include golden, brown, tan, and greenish, depending on minerals.

One of its earliest recorded names, Har decher, literally meant "Red One" in Egyptian.

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.

Nanophase material

nanophasenanophase materials
Martian dust is reddish mostly due to the spectral properties of nanophase ferric oxides (npOx) that tend to dominate in the visible spectrum.

Iron(III) oxide

Martian dust is reddish mostly due to the spectral properties of nanophase ferric oxides (npOx) that tend to dominate in the visible spectrum.

Hematite

The specific npOx minerals have not been fully constrained, but nanocrystalline red hematite (α-Fe 2 O 3 ) may be the volumetrically dominant one, at least at the less than 100 μm sampling depth of infrared remote sensors such as the Mars Express OMEGA instrument.

Titanium

In addition, remote sensing observations of atmospheric dust (which shows slight compositional and grain size differences from surface dust), indicates that the bulk volume of dust grains consists of plagioclase feldspar and zeolite, along with minor pyroxene and olivine components.
