What Colour Would the sky be if the sun was blue?

What Colour Would the sky be if the sun was blue?

If the sun became blue with the same luminosity, the sky would just be bluer. The current blue sky is due to rayleigh scattering, which removes most of the light except blue.

What color would the sky be if the sun was a different color?

This light would then Rayleigh-scatter in the atmosphere, with the result as described above: the unscattered sunlight would be redder than the actual color of the sun, and the sky would be bluer or perhaps more violet, shifted to higher frequencies.

Would the sky be blue if the sun was red?

There’s also some trickery with how our eyes perceive light (why it is blue, not violet). Now, if the sun was a red star, there would be little/no blue light to scatter.

What is the rarest sky color?

blue sky
The vast blue sky and the many blue clothes out there may trick you into thinking this color is common in the natural world but, think again. When was the last time you glimpsed a blue petal, insect or bird? They’re out there, but not many. Blue is one of the rarest of colors in nature.

What if the sun was a red star?

Red dwarfs stars are smaller and cooler than our relatively average star, the Sun. We think that many red dwarf star systems may have habitable, Earth-like planets that orbit them but replacing our Sun with a red dwarf would be rather disruptive to our Solar System and home planet.

What if the sun was black?

Well, the black-hole-Sun will not be giving out any light or heat, so prepare for miserable existence in freezing cold and pitch black environment. You will not be able to see the Moon and our neighbor planets on the permanently dark sky anymore, only stars.

What if the sun was green?

That is why we can see so many different colors in the natural world under the illumination of sunlight. If sunlight were purely green, then everything outside would look green or dark. The sun emits all colors of visible light, and in fact emits all frequencies of electromagnetic waves except gamma rays.

What Colours don’t exist?

That’s because, even though those colors exist, you’ve probably never seen them. Red-green and yellow-blue are the so-called “forbidden colors.” Composed of pairs of hues whose light frequencies automatically cancel each other out in the human eye, they’re supposed to be impossible to see simultaneously.

Which color does not exist?

Magenta
Magenta doesn’t exist because it has no wavelength; there’s no place for it on the spectrum. The only reason we see it is because our brain doesn’t like having green (magenta’s complement) between purple and red, so it substitutes a new thing.
