Kaweco Paradise Blue, formerly called Kaweco Turquoise, is a gentle green-blue that shades beautifully. It reminds us of the discontinued Caran d’Ache Caribbean Sea.
Pelikan Turquoise falls on the blue side of the turquoise range, and also features great shading, albeit blue and blue rather than blue and green.
Two beautiful turquoise inks.
I like them separately and together.
