When the atmosphere is thicker, it scatters more light. This results in longer wavelengths of light, like red and orange, being able to penetrate deeper into the atmosphere. At noon, the Sun appears white due to the scattering of all colors of light by the atmosphere. However, with a thicker atmosphere, the scattering of shorter wavelengths, like blue and violet, will be more significant, making the Sun appear more red-orange.
