It's a light blue universe after all
Scientists have seen our universe, and it's a pleasant shade of pale turquoise. The scientists have added up all the wavelengths of all the light of the universe, and averaged out, it comes to a nice shade well suited "for teeshirts, or home decorating". They're calling the colour "Cosmic Spectrum Green." If you don't like it, just wait. As the universe gets older, the spectrum average will go from blue to red.
