the true colour of the star / galaxy

Is it really the true colour, not a colour which some astronomer has picked, to look pretty?

I am afraid you are getting confused with astrophotography and spectroscopy, but even with that in mind this is a bit of a silly question. I referred to hydrogen absorption spectra, and the absorption lines fall very comfortably within the visible spectrum.

If you look out of the window of your spaceship, would you ever see these colours?
