Cosmic Latte: The Average Color of the Universe

Astronomers have determined the average color of the universe by computationally averaging the light from a large sample of galaxies. The resulting color is a shade of beige, represented by the hex code #FFF8E7.

This average color, nicknamed 'cosmic latte' after a public contest, was derived from analyzing the light emitted by 200,000 galaxies in the 2dF Galaxy Redshift Survey.

The composite color represents the overall spectrum of light from the universe, with emissions across all parts of the electromagnetic spectrum.

Over the past 10 billion years, the universe's average color has shifted towards redder hues, indicating an increase in the prevalence of redder stars.
