After looking at my new complete ANS9 sticker set that I just bought, I've noticed something interesting: the base stickers in this series are much darker in color than in the previous modern series I've got (ANS1-ANS8 and the two Flashback series). Did this thing continue into the future modern series (i.e., ANS10, ANS11, 2014 S1 and 2015 S1) or was this just a one-time fluke?
