The sky appears yellow mainly due to the way sunlight interacts with the atmosphere under certain conditions. Severe thunderstorms can cause a yellow tint as the clouds scatter blue light and let yellow light become more visible. Additionally, factors like poor air quality, wildfires, pollution, and dust in the atmosphere can also change the sky’s color to yellow by scattering the blue light differently. This yellow sky is often seen as a sign that a storm is coming or has just passed and is not something to worry about. The yellow color arises because the sunlight loses its blue wavelengths through scattering, leaving more yellow and red wavelengths visible near the horizon or under specific atmospheric conditions.
In short, the sky is yellow because the sunlight’s blue light is scattered away by storm clouds, pollutants, or other particles, making the remaining light seen directly by the eye richer in yellow hues.
