Photography Challenge Week #5

Just a fun fact about snow 🙂
While many think that snow is either white or blue, its ‘colors’ range from yellow and orange to green and even purple, but…believe it or not, snow is actually colorless1. According to the National Snow and Ice Data Center, “the complex structure of snow crystals results in countless tiny surfaces from which visible light is efficiently reflected. What little sunlight is absorbed by snow is absorbed uniformly over the wavelengths of visible light thus giving snow its white appearance.”

Cold-tolerant algae are small, photosynthetic organisms which grow on snow and ice in the polar and alpine regions. Different strains of algae can color the snow yellow, red, orange, brown, green. Of course, the snow acquires its color after it has fallen. You may see snow that falls pink, brown, orange or red, if the air is filled with dust, pollutants or sand. Orange snow fell over Siberia in 2007 and Krasnodar (Russia) was covered by pink snow in 2010.
