what color is the sky
As far as wavelengths go, Earth's sky really is a bluish-violet. But because of our eyes we see it as pale blue.
The color of the sky can vary depending on the time of day and atmospheric conditions. During a clear day, when the sun is high in the sky, the color appears to be blue. This is because of a phenomenon called Rayleigh scattering, where the molecules in the Earth's atmosphere scatter sunlight in all directions. The shorter wavelengths of blue light are scattered more than the longer wavelengths of red light, making the sky appear blue.
To determine the color of the sky, you can simply look up at the sky during daytime when there are no clouds blocking your view. Take note of the color you observe.
It's important to keep in mind that the color of the sky can change. For example, during sunrise or sunset, the sky can appear to be a mix of colors including shades of red, orange, pink, and purple. Additionally, weather conditions such as clouds, pollution, and particulate matter in the atmosphere can affect the color of the sky.
