A shade of Amber used in Theater Lighting Gels. It is fairly warm and pink-ish and is highly popular for lighting almost any sort of daytime scene in a play -- outdoors and indoors... it helps prevent the actors from seeming washed out and corpse-ish.

The reason it is named Bastard Amber (besides making hordes of middle school theatre students giggle madly) is because it was actually a mistake. The company was trying to mix up a batch of normal Amber and something went wrong. However, when a director picked it up, he really loved it. Then they had to reverse engineer it and figure what screwed up the color in the first place, so that now they could do it on purpose.

Generations (well, I exagerrate. Not quite generations) of techies, Directors, and theater-types have been grateful ever since.
