I was just thinking... As far as flashlights go, if you have a really bright LED flashlight that lights up on the bluer end of the spectrum, couldn't you cover the end with a yellow or orange film, to warm the color up a bit? Using, say, a stretched-out bit of balloon? Or a thin layer of yellow nail polish, if you have some, and don't mind it being permanent... I know my dad used to have red plastic film (maybe mylar) laying around to put over his big maglight for when he wanted to go dig up nightcrawlers for fishing.
