Taken on a cold day in the Vatnajökull ice cap in Iceland. The blue color of the ice comes from its clarity while filtering away most of the color spectrum of the light except for the blue.

The harsh and contrasty light in the cave made a single exposure impossible. This is a manually blended image from 6 exposures. Although I like to do things in a single exposure but in this case the technical limitations of the camera sensor could just not capture what the naked eye saw.
