Several years have "blue tints" like this; where it's not just a color being darker in a print run but the color present in places it should not be. 1968 football and 1971 football are pretty obvious, 1967 baseball has them in at least a couple of the series.
1957 has at least two of each card, some have red tint, blue tint and a "proper" one.
I count these as true variations, though it makes my spreadsheets a pain to manage sometimes.
