If you live in Perth you may be familiar with the green flash at sunset. The phenomenen is caused by light refracting at unequal speeds across the spectrum. Higher frequency light (greens and blues) curves more than lower frequency light (reds and yellows) so the greens are left visible after the sun has set.

Yeah, there's that, or there's Trigg's Marc Lee flaring up in his bright green hat.
