Red planet wallpapers

Mars gets its color from iron oxide in the dust, which is why rover photos lean toward butterscotch and rust more than true red. This preset keeps that range: a near-black base with soft blooms of rust, orange and pale sand.

Warm wallpapers can make a screen feel dim in the evening because white windows look cold against them. If that bothers you, swap the darkest color for a deep brown so the contrast with your apps is less sharp.
