The red tint in the sun is caused by the scattering of sunlight as it passes through the Earth's atmosphere. When the sun is low on the horizon, its light has to pass through a thicker layer of the atmosphere, which scatters the shorter blue and green wavelengths of light, leaving the longer red and orange wavelengths to dominate the sky. This is why sunsets and sunrises often appear red or orange in color. Additionally, particles and pollutants in the atmosphere can also contribute to the red tint in the sun by scattering and absorbing certain wavelengths of light. **
