Most of us are aware that almost all of the PIEDMONT 460 (Factory 42) backs are found with a much lighter shade of blue than the
PIEDMONT 150, 350 and 460 (Factory 25) Series backs.
It appears that American Litho. switched to a lighter shade of Blue ink in the final T206 print runs of these in the Spring of 1911. This
appears to be also true in the printing of the fronts. For example, every PIEDMONT 460 Factory 42 Blue portrait Hal Chase cards that
I have seen, are a lighter shade of Blue than the original 350 Series cards of Chase (that have a deep Blue color).

Furthermore, the use of this lighter Blue color appears to continue into the subsequent T-card issues with T206 fronts. And perhaps,
this may possibly explain the switch to Blue ink in the printing of the captions in the T213-2, T213-3, T214, and T215-2 issues.

Some more T206 Chase examples from the 350 series that illustrate the consistency of the deep blue coloration.





Shows us some of your PIEDMONT 460 Factory 42 cards with Blue colored Fronts in order that we may have a better sampling of the varying shades of blue.
