Can there ever be too many deep teal blue-green inks? Not in my world. Diamine Teal ($14.94 for 80ml bottle) is a deep ocean blue-green color. Its got a bit of shading in a finer nib pen but is more evident in wider strokes and in my painted title. The color is muted enough and dark enough to work-appropriate but interesting enough to keep the most discerning pen geek engaged.
When I loaded Diamine Teal into my TWSBI 580 Christmas Green I was immediately reminded of another favorite, DeAtramentis Petrol. However, DeAtramentis inks are a little more watery than Diamine and the Petrol color is a bit more vibrant than the Teal. So, clearly, I have reasons to need both.
Akkerman #24 Zuiderpark Blauw-Groen is also very similar but is a little darker and has a visible sheen. Akkerman inks are also a bit more expensive and harder to acquire in the States so if you’re looking for a good alternative to #24, I think Diamine Teal is a very close alternative.
