I have #84 in orange red. On this one I can see a hint of oragnge in the corners. What would cause a color shift like this? Or is it another issue that I have overlooked in Scott? Thanks for your input.

re: Color shift on Sweden #84?

Hi, Professor,

Looks like your stamp sulferized (frequently called "oxidized). That color ink wasn't very stable, so this happened somewhat often. If soaked in hydrogen peroxide (3%, use a new bottle), it will turn the color back to about what it was. The color will likely start changing right away - carefully swirl/move it around a bit with tongs. 30 seconds to a minute or so should do it. If not, put it in a bit longer. Be sure the rinse the stamp in lukewarm clean water a few times, then let it dry in a drying book. Should do the trick!
