No big reveal party? I'm imagining you revealing purple and confuse the people that:
a. Don't understand that "red" (pink) and blue make purple.
b. Don't know you're having twins and now think you are having a hermaphrodite.
We were thinking of doing two "reveals" or something of that sort. But...in the end, all of our family are several hours away. It'd take a lot of coordination and cost to get people together to do a reveal or get some sort of "remote" reveal going.
