In the Antarctic and high mountains, snow appears in colors like pink, purple, red, and yellowish-brown.

Infact verdict: Mostly True (72/100).

The claim that snow appears in colors such as pink, purple, red, and yellowish-brown in the Antarctic and high mountains is partially supported by the evidence. Various credible sources explain that snow can indeed appear in different colors due to factors such as the presence of algae or impurities. For example, red or pink snow, often called 'watermelon snow,' is caused by algae in polar regions and high altitude areas. However, the evidence does not strongly support the presence of purple or yellowish-brown snow in these contexts. Thus, while some aspects of the claim are true, it is not entirely accurate as stated. The factual support from the web evidence allows us to consider this claim mostly true but not entirely accurate.
