What causes red skies?

The red skies effect typically occurs after heavy thunderstorm during the day, where the rain tends to wash “large particles” out of the air.

Such particles absorb more light and scatter its wavelengths more equally, making the colours more muted.

In their absence, the colours seen in the sky can appear more intense.
