In reality, these blushes come from an embarrassment of algae.

 

Thanks to their photosynthetic prowess, algae produce a large

amount of the world’s oxygen, and form the foundation of most

food webs.

 

While it’s unclear exactly what spurs the blooms, the color — often

red, but sometimes green, gray or yellow — comes from pigments

and other molecules that the snow algae use to protect themselves

from ultraviolet light. These hues absorb more sunlight, causing the

underlying snow to melt more quickly. This can change ecosystem

dynamics and hasten the shrinking of glaciers.
