Just for reference too, there's a section added into the Bespin rulebook about Dice Types:
Some abilities refer to a die's type. A die's type is either
"attack" or "defense."
• Blue, Red, Green, and Yellow dice are attack dice.
• Black and White dice are defense dice.
I'm still hoping they'll make a new defense die, like a brown die or something that's halfway between the White and Black die.
