Do you know what was the first color of the universe?

Our curiosity and wonder about it is as boundless as the universe itself. The universe consists of infinite space-time, some of which scientists know, but most of which remains unknown. And with so many complex questions, a very innocent question is, what was the original color of the universe?

The first color of the universe

The answer can be found recently in the book 'The Universe in 100 Colors: Weird and Wonderful Colors from Science and Nature', written by Tyler Thrasher and Terry Mudge. Talking to them, a report was published by science and technology site 'Popular Science'.

At three hundred and eighty thousand years old, the color of the universe was a bright-warm shiny pitch orange. After that, the temperature of the universe drops to three thousand Kelvin or 2727 degrees Celsius (4938 degrees Fahrenheit).

Before this time the plasma of the infant universe was so dense that light could not pass through it. Before any matter could form in the universe, it needed to cool down enough to allow the formation of atoms. And if atoms are not created, colors cannot be created.

The average temperature of the universe today is just under three Kelvin, a direct drop from the temperature of three thousand Kelvin in the ancient universe. This hypothesis is arrived at by calculating the 'cosmic background radiation', which is considered to be central to the Big Bang theory. The temperature in the early universe was uniformly distributed, with wavelengths matching that of a blackbody.

It is an object or thing that shows color based solely on its temperature rather than the material it is made of. If humans could observe this color along the space-time continuum of the early universe, our early universe would have been the color of a warm orange campfire.

And that bright orange color will gradually darken and fade until the universe is about a hundred million years old, when the first stars are born, gradually forming the universe we know today.
