 Snow actually can be different colors. Most people believe that snow is white or grey after it gets dirty, but there's more to it. To be super specific, snow is actually translucent since it's made up of ice crystals. However, because of how those clear crystals reflect light, snow actually appears white to the human eye. When dust and algae make an appearance though, it can look purple, orange and green. Pink snow, known as watermelon snow, fell in Russia in 2010. It actually had a sweet smell and taste and I kinda want to eat some now.
