Are the pictures taken by the Hubble Space Telescope in color? Or do astronomers add color in after they are taken?

The Hubble only takes photographs in greyscale.
Explanation:
The Hubble uses a CCD camera which only records greyscale images.
The Hubble takes a number of different greyscale photographs at different wavelengths. Each of the photographs is coloured and then superimposed to give a full colour image. Non visible wavelengths are given an artificial visible colour.
