Notes: I ordered this sample of Sheaffer Turquoise because I wanted to compare to the bottle of vintage Peacock Blue that I have. They’re pretty close, but the Peacock Blue has a little bit more green in it, and doesn’t shade as much as the Turquoise. The Turquoise performed very nicely, had great shading, and wrote nice and smooth. The color was pleasing as well. I used all of the blues I had inked up in the comparison section to give a better idea of what the shade was. While I don’t think it’s a direct replacement for the discontinued Peacock Blue, it’s pretty darn close.
