Original Note:
“Glacier ice is blue because the red (long wavelengths) part of white light is absorbed by ice and the blue (short wavelengths) light is transmitted and scattered. The longer the path light travels in ice, the more blue it appears“ https://en.m.wikipedia.org/wiki/Blue_iceberg https://www.usgs.gov/faqs/why-glacier-ice-blue#:~:text=Glacier%20ice%20is%20blue%20because,the%20more%20blue%20it%20appears.
