... right in their CA chip guide (though they do call the inserts "orange" and red rather than "yellow" and red; I'm virtually colorblind, so what do I know?).

BTW, the Eastman book also says the chip has a round inlay rather than hub.
On the other hand, he does have a picture of the chip which clearly shows both three sets of inserts (the book is printed in black and white, so there's no way to tell what colors are shown) and a hub inlay.
