What is the blue color in glaciers?

Glacial ice is a different color from regular ice. It is so blue because the dense ice of the glacier absorbs every other color of the spectrum except blue - so blue is what we see!

What causes snow to be blue?

"When snow appears to be blue, it's very pure. The phenomenon is called blue coloration in photography. Light has different wavelengths that we perceive as colours, and blue light is the light that goes through ice most readily. The same phenomenon makes the sea and the sky blue," says Jonasson.

Why is the water around a glacier blue?

That is, a snow patch becomes a glacier when the deepest layers begin to deform due to the weight of the overlying snow and ice. Because the red (long wavelengths) part of white light is absorbed by ice and the blue (short wavelengths) light is transmitted and scattered.
