When looking at galaxies through a telescope, a galaxy will be primarily blue or red, and the color depends on the color of the stars. For galaxy products and product ideas - like wallpapers, cakes, placemats, bedding, and more - the traditional galaxy color scheme includes black, purple, pink, and blue shades.  However, galaxy colors can also be more on the black and purple side of the spectrum, or black and blue, or purple and blue. There are also galaxy designs in green, aqua, red, and pastel shades that work together beautifully.
