I have this stamp with two colors of ink. Any thoughts what this is?

I do not think it is ink, I appears to be a color changling. Perhaps a chemical or badly faded?

It's a chemical reaction. I have many of these that have been turned partially or completely blue.

P.S. You may want to check 'HOW TO DETECT DAMAGED, ALTERED AND REPAIRED STAMPS" by W. Schmid ©1979 published by the PALM PRESS. The book may give you an indication of the chemical tat changed the color.

I bet the color change was due to Hydrogen Peroxide. My guess was that someone was using Hydrogen Peroxide to reverse oxidation on a 6¢ James A. Garfield and some of it splashed on the 1¢ Benjamin Franklin (Sc# 552/632).

Thanks for the info! I have a variety of color varieties and/or changlings that are fun to look at but not sure what they are. I have an orange Scott c25 as well a pair of scott 822 that has a shiny substance on parts of them that changed the ink on it or didn't let the ink adhere.

Some people think it's fun to play games with chemicals other times it's accidental.

I doubt Hydrogen peroxide would do that to it but some other chemical would - maybe a drop of bleach
