red sunset

Crimson twilight horizon

A red sunset is the reddish-orange coloring of the sky at sunset, caused by sunlight traveling through more atmosphere and scattering shorter wavelengths.

Red sunsets often appear more vivid when dust or pollution particles fill the air.

The old weather proverb "red sky at night, sailor's delight" suggests they predict fair weather: We sat on the porch watching the red sunset.
