At this time of the year, it looks all white.

Snow cover as thin as 1 m can be seen white because all sun light wavelength is reflected. In contrast to snow, ice with the thickness of several m to 10 m absorbs long wavelength like red more than short wavelength like blue. That is why glacier ice is blue and snow is white. But a tunnel dug under a 2 to 3 m thick snow is the world of dreamy blue.

There are many colors in the artic, including grey and blue. I believe we have "all the colors of the rainbow" and the light are changing, many times during the day especially in the morning and the evening. Many interesting light phenomena occur on the sky and in the snow, for example "sun dogs".

As you know, the latitude is very high in the arctic regions. They have a very long day during summer and a very long night during winter. During summer, snow is gone from the ground. The ground looks like light brown in several regions. The sea is dark blue and sky is dazzilingly light blue or white. During winter, the sea and land are covered by white snow and ice. But it is dark there.
