When I was a kid I soaked many stamps off of pink envelopes that came from where my dad worked. Of course the paper and ink was modern, and the pink transferred into the stamp differently than in photo. That is, they were slightly blotchy or streaky with the pink, and never perfectly uniform.
pink = (not a very good) portmanteau for pink ink, just like our emoji Pinky here would tell you.
