The blue color is sometimes wrongly attributed to Rayleigh scattering, which is responsible for the color of the sky. Rather, water ice is blue for the same reason that large quantities of liquid water are blue: it is a result of an overtone of an oxygen–hydrogen (O−H) bond stretch in water, which absorbs light at the red end of the visible ...
Icebergs may also appear blue due to light refraction and age. Older icebergs reveal vivid hues of green and blue, resulting from a high concentration of color, microorganisms, and compacted ice. [5] An iceberg of “electric blue” colour in the waters off Sermilik fjord near Greenland in 2009 was named by locals the "blue diamond". [6]
A large piece of compressed ice, or a glacier, appears blue, as large quantities of water appear blue, because water molecules absorb other colors more efficiently than blue. The other reason for the blue color of glaciers is the lack of air bubbles.

Icebergs are generally white because they are covered in snow, but can be green, blue, yellow, black, striped, or even rainbow-colored. [22] Seawater, algae and lack of air bubbles in the ice can create diverse colors. Sediment can create the dirty black coloration present in some icebergs. [23]
A glacier in the Transantarctic Mountains.Blue ice is seen as a lighter blue in the photograph, while the darker blue is formed by re-frozen melt ponds. Blue-ice areas have a generally smooth and often [1] rippled appearance, a blue colour [2] and a sparseness of bubbles in the ice. [3]
