The sky appears purple in certain conditions due to the way sunlight interacts with the atmosphere. Normally, the sky looks blue because of Rayleigh scattering, where shorter wavelengths of light (like blue) are scattered more than longer wavelengths (like red or yellow). However, when the sun is lower in the sky, such as during sunset or sunrise, the light has to pass through more of the atmosphere. This causes more scattering of the shorter wavelengths, allowing the longer wavelengths (reds and oranges) to dominate. If there's a mix of both red and blue light during these times, it can create a purple hue, especially when the atmosphere is filled with particles, dust, or pollutants that enhance this effect.
