Can the sky be different colors on other planets?

Absolutely, due to differences in their atmospheres and surface compositions, other planets' skies

can have a variety of colors. For instance, the soil of Mars contains iron oxide, or rust, which gives the

planet's sky a reddish appearance. The sun's location and atmosphere affect the hue of

the sky on several planets. The following are a few instances of sky hues on several

planets:  Mercury: Black, Venus: Orange, Earth: Blue, Mars: Red or blue,

Uranus: Blue or turquoise and Titan (a moon of Saturn): Yellow, orange, or brown.
