Color of Milky Way? Red, Bright and Blue

Turns out the Milky Way is aptly named, with the overall color of our galaxy resembling the shade of fine-grained spring snow in early morning light.
Splitting the light into its component wavelengths, however, reveals a redder-than-average color for the Milky Way's core, and sky-blue spiral arms.
The portrait, pieced together from 1,000 similar galaxies culled from the Sloan Digital Sky Survey, shows the Milky Way as it would appear from perspective of another galaxy, albeit one whose inhabitants have vision similar to humans.
According to researchers, Milky Way is among the reddest of spiral galaxies, meaning that its star-forming days are coming to an end.
The light from the Milky Way closely matches the color of a standard incandescent light bulb, well within the range of what the human eye perceives as white.
