Purple and orange as very late sunset sky when you just forgot that you waited whole day for it. You run outside and look out for the sun but it's already too late and all you see are purple sky and pink and orange clouds far west. First orange becomes red, then pink becomes blue, then all become black... Stars will come later at night. You turn back and make new pot of coffee. Maybe you will get out one more time to look at stars but maybe not today.
