Bring out the colours of stars

From reds to yellows to blues, here's how to reveal the subtle tones of stars in your images

- 

Star colour is often mentioned when we describe the night sky. From the red of Betelgeuse, to the yellow hues of Capella and steely blue-white of Vega, colour descriptors often promise more than the visual or photographic view shows.

There are several reasons for this. For one, when we describe a star as red it may conjure up the image of a bright pure red object shining against the blackness of space, but in reality the colour will appear far more subtle than this, often as a hint of orange. Betelgeuse and Aldebaran are fine examples in the winter sky.
