robert aTheories and more theories:
It's possible that smaller companies/retailers on the east coast (blomes, close, baltimore news) were allowed to pick which color background they wanted for their product(s).
Baltimore News picked blue, Old Put used red, etc.
This could also explain why certain colors within E94 seem to be scarcer than others. Perhaps those products weren't as popular.
The one and only "e94" overprint that I have is a Turqoise Kleinow with a Blomes Back. I've seen another Turquoise Kleinow with a Blomes Back.
These are so scarce that it's pretty much impossible to do a study of what color backgrounds are found with what overprints, but it would be interesting to see if there are any patterns there.
