Did you know?... Many stars appear yellowish white to the human eye because of their contrasting colour to the night sky.

In fact, stars can also appear to have a red or blueish glow. In dark conditions, the human eye finds it easier to view objects as either black or white. If you are in a pollution-free area and the sky is clear, you should be able to make out other colours once your eyes are accustomed to the darkness.
