The presence of very small particles in the atmosphere can scatter sunlight in a way that enhances the red hues seen during sunset. This scattering effect, known as Rayleigh scattering, is more effective at shorter wavelengths (blue light) and less effective at longer wavelengths (red light). When the sun is low on the horizon, its light passes through more of the Earth's atmosphere, which scatters the shorter wavelengths and allows more of the red light to reach the observer's eye, making the sunset appear more red.
