Sep 23, 2020 · Yellow is caused by charged paticles in the solar wind striking oxygen high in the atmosphere. The oxygen then emits yellow light. This happens constantly on your planet. Because of the near constant haze, the pure yellow light emitted by oxygen is diffracted in the haze, such that the entire sky glows yellow.
Most colors would be possible. The two items that determine what color the sky is is the color of the sun and what is in the atmosphere. Having a red star will be the easiest in making the the sky shades of red, since that is the primary wavelengths coming from the star.
(Ah, and our Sun is not yellow. It is white with a very very very slight yellow tinge. The same would go for a "blue" star -- it would be white, with a very very very slight blue tinge. Only a red star can be truely red, but then if it were as small in the sky as our Sun it would be so much less luminous that the sky would appear black ...
Jul 9, 2020 · Every sky, even sky on Mars or Jupiter tend to be blue. If you atmosphere is Earth-like it will be blue. Only sunsets and sunrises would add some tints to horizon, but it still would be more or less red (and would add redish tint to suns) Reason is simple: color of a sky is defined by Rayleigh scattering.
If the planet's sun was very hot, the sky would look a deeper blue, while cooler stars would give the sky a lighter blue to almost white look. When the sun gets to 3000k and below, the sky starts to take on an orange/brown tinge. Like on earth, the horizon is the lightest in color and the zenith the deepest.
May 24, 2015 · The hues of the refracted light mix together to create the colour of the sky - if red and yellow are refracted most, you will end up with an orange sky. Changing Sky Colour. To change the colour of the sky on your world, simply change the light that's hitting the atmosphere, or change the atmospheric composition.
Feb 15, 2016 · A "cold" star (around 3000 K or 5000 °F) will be red. Meaning your sky (and everything else you look at) will be red. As the star gets hotter, the color will progress through orange and yellow, then start becoming whiter and whiter, but the sky will always tend towards the shortest wavelengths visible, so it could look red, yellow, green, or blue.
Aug 25, 2022 · The reason our sky is blue is a mixture of 2 phenomenan called Rayleigh scattering and blackbody radiation. Rayleigh scattering says that shorter wavelengths of light (blues and purples) are more likely to bounce of the air molecules compared to longer wavelengths of light (reds and yellows).
If it's a really dim red dwarf (like an M8) your sky might take on a somewhat orange/brown tinge even at noon (due to sever lack of longer-wavelength light). Noon: A darker, greyish-blue (maybe brownish-orange) at zenith getting whiter/grey towards the horizon. The sky overall is much darker in color than Earth's.
Nov 18, 2021 · Mars normally has a pinkish sky with blue sunsets because Mars has fine dust in the air. A wetter Mars would not have the same coloration. Earth's sky is "blue", but I think is a difference between the robin's-egg blue of some seasons and the deep almost iridescent hues of late summer in the eastern U.S., where dust from as far away as the Sahara may have an effect.
