Mars appears red due to the presence of iron in its rocks and metals, which oxidizes to form ferric oxide or rust. However, parts of Mars exhibit other colors such as yellow, brown, green, or butterscotch, but dust storms obscure these regions, enhancing the red appearance. The document also briefly mentions an upcoming topic on mirages.

oxygen reacts with iron to
form ferric oxide or rust
which is red in colour.

butter-scotched colour.

But because of dust storms
on mars, the rust covers up
the non - red regions of mars
and thus it appears to be red
in colour.
