The chip on the left is off white.
The chip on the right is white.
The chip on the left has darker blue inserts.
The chip on the right has lighter blue inserts.
The edges of the chip on the left aren't beveled/rounded.
The edge of ONE side of the chip on the right isn't beveled/rounded BUT the other side IS beveled.
WTF (pardon my French)

Last one for today, I promise.
