I did not add the blue color to my photo. However I do use the NIK FILTER program for editing 90% of my pictures. This could enhance the blue color in the photo. To understand better, it is usefull to read the WIKIPEDIA article concerning the blue color of ice. This is mainly related to the composition of the ice (thickness and compression).
I also invite you to have a look at my photo (posted on FLICKR -3 september 2022) concerning DIAMOND BEACH. Here you see ice blocks with different colors (white, transparent and blue). The distance between the two locations is about 500 meters. Pictures taken on the same day.
