67 / 68 Heater Control

[MyRed67]

 I just recently found out that even though interchangeable, original 67 and 68 Heater Controls are not the same, they have different color background.   original 67's are black, and 68's supposedly blue, is this correct?  If so what are the repops like?

They both have black backgrounds and both have a slight tint on the lettering (with 67 being a greenish tint and 68 being a slightly bluish tint), but it's easy to tell the 67 from the 68 because they have different verbage. (Also note that the fonts on the repops aren't quite right.)
