The only information I could find was very general and basically said that it was due to light being scattered by the atmosphere. But I don’t understand how is the process different on the two planets? Otherwise the sunset would be the same colour on both of them
I tried asking /askscience but nobody replied

Mars has a different balance of gases in its atmosphere compared to Earth. Different gases absorb and re-emit different frequencies of light. The Nitrogen-Oxygen mix of Earth’s atmosphere scatters blue light more, leaving more red behind when the sun is near the horizon. The CO2 atmosphere of Mars is better at scattering red light so that you mostly see blue in the same situation.
