When we colonize Mars, I think we should only populate it with redheads. In this way, we will demonstrate to the universe that Earth has a sense of humor.
Also, this will enable the recessive red hair color gene to thrive. I am concerned that their pale skin might not give them sufficient protection in the thin Martian air, but, you have to expect everyone will be living in domes at first.
Eventually, when Mars is terraformed, only people with long memories will recall that Mars was known as “the red planet” for a reason other than the people’s hair color.
