Scattering and Shadows at Sunset

On a clear day shadows tend to have a blue cast because they are being lit by scattered light from a blue sky. This isn't always obvious unless you have a white background, the contrast can be even greater toward sunset when the direct light is reddened.

The snow on the hills and a nearby drift reflects a warm glow from the low sun.

Shadows cast on the snow are distinctly blue compared the the snow in sunlight.

The next evening a patch of cloud gave a colourful sunset, but it wasn't enough to dominate the scene.

The foreground was mostly lit by the sky overhead and is obviously blue by comparison.
