How would the sky look if our 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 would happen if the sun was red?
It is calculated that the expanding sun will grow large enough to encompass the orbit’s of Mercury, Venus, and maybe even Earth. Even if the Earth were to survive being consumed, its new proximity to the the intense heat of this red sun would scorch our planet and make it completely impossible for life to survive.
What color would the sky be with a red star?
All that being said the light from the star would still be white to us (not red) just as our sun doesn’t look “yellow”. If the sky is clear you will still get Rayleigh scattering and it will appear blue (assuming same atmosphere).
Does the sun affect the color of the sky?
The angle of sunlight as it enters the atmosphere also affects the color of the sky. During sunrise or sunset, when the Sun is close to the horizon, the light must travel through more of the atmosphere than it does when the Sun is overhead.
What would happen if the sun changed color?
Because blue light scatters more easily than any other color of light, the sky appears blue during the day. And, in fact, if our sun were a different size, color, and temperature, our sunsets would look different.
What would happen if the sun was a different Colour?
The color of a star is dependent upon its temperature. If the sun was a different color then it would be either hotter or colder. Either one would be bad. A pretty small difference in the output of the sun would have big effects on our planet, and a change big enough to change its color is not small.

Can our sun be blue?
Here on Earth, the atmosphere plays a role in the color of the sun. Since shorter wavelength blue light is scattered more efficiently than longer wavelength red light, we lose some of the blue tint of the sun as sunlight passes through the atmosphere.
