My favorite for stuff is Lime Green. I carry a Lime Green UKSL4 light in my pocket, and it's fun to pull it out at 60 feet and show it to people... It will look bright yellow. It looses all the green tint, and side by side with a yellow one, you'd swear they are the same color... then you come up and presto... turns back into lime.
Very neat for showing the color shift.
