* Clouds being illuminated by red-orange light - high clouds are translucent and can be seen against the sun, lower dense clouds block the sunlight and appear dark against the sun, but bright looking away from the sun. Most spectacular sunset pictures show red-orange clouds glowing in front of a relatively dark clear sky. | * Clouds being illuminated by red-orange light - high clouds are translucent and can be seen against the sun, lower dense clouds block the sunlight and appear dark against the sun, but bright looking away from the sun.

The following screenshots of a very coloured sunrise in which successively the diffuse scattering and the Mie scattering components are removed illustrate this - in a clear, Rayleigh dominated sky the blue sky color essentially remains: | |||
