Good Evening,
As fun as identifying a stamps color from 1863 could POSSIBLY be (given time, etc.) I'm hoping my scan can help sort this stamp out. I am not well versed in colors of red - let alone colors of red that are over 150 years old.

Choices from Stanley Gibbons are:
"Rosy Mauve"
"Dull Rose"
"Vermillion"
Thanks for looking!
