This is a big topic of discussion at our house and this coming weekend, all the kids are coming home to decorate our yard and porch. We do a pumpkins/candy corn kind of theme, although our sons--especially the 6-year-old--would prefer blood and gore. We have candy corn and orange lights and candy corn and pumpkin yard decorations. I think I'm going to order jack o' lantern luminarias and put battery-operated tealights in them...also order a candy corn wreath.
Has anybody else noticed that in the past few years, purple and poison green have apparently joined orange and black and yellow as Halloween colors?

like the purple for wizards' capes and the green of witches' or Frankenstein's monster's faces?
Any other ideas? What will you do to decorate your place?
