Changing galactic color

[MrBatman]

Is there a way of changing the color of the galaxies? Currently they are dusty grey, I'd like to alter them into the blue a little. How would I go about doing this?

I think it is specified in the source, so you would need to edit it and recompile.

Please remember that if you make the elliptical galaxies blue, this would be completely incorrect.
