 When I was writing my SF novel Water to Water, I wanted the sky at some latitude (I forget which) to be multicolored. I did enough research to decide it was plausible, but I remember none of it . . . .

 The plants on Barrayar (on topic for once) are red and brown instead of green (Ekaterin remarked that a green Barrayan plant would be very sick.) because the plants use a different chemical. This appears to be a common SF trope but do we know of any other chemicals that would work?
Also the sky on other planets is written to be just about any color. Pink or butterscotch on Mars?
