Wedding guest asked to leave when blacklight turns her dress into a banned color during the reception: 'I wore a dress that looks white under a black light'

You don't wear white to a well-lit or naturally-lit normal wedding. Apparently, you also don't wear yellow to a blacklight wedding either—so says this bridal party who asked a guest to leave after declaring her yellow dress to be inappropriate under the chosen ambient lighting.

While we've read about some ridiculous situations where wedding guests have worn what might-as-well-be wedding dresses to their friend's or family member's wedding affairs, I think it's fair to say that this is not one of those situations. Of course, if you were a bee or a butterfly or some other creature that can see the ultraviolet spectrum, you might be able to be willingly held accountable for wearing such a color. 

I thought blacklights were pretty cool, too, when I was a teenager, but I can't imagine having blacklights for such an event as a wedding now. Still, accusing someone of not anticipating the lighting of the wedding reception is strange and petty, especially when the bride herself didn't seem to care.
