Recently, I became obsessed with light blue inks especially if they are turquoise, whatever that means. Turquoise is described as greenish blue but most inks with that name are basically blue with one or very few dyes. Chromatography with these inks is not very exciting. Many of them are, however, very beautiful (to me at least) and have uncommonly good writing properties perhaps because of their simplicity and relatively low dye content. Sheen is possible with some of these ink, at least on Tomoe River paper, but water resistance is uniformly not good. That said Pelikan 4001 Turkis Turquoise, Noodler's Midway Blue (ok, not a turquoise for sure), Noodler's American Eel Turquoise, and of course, KWZ IG (iron gall) Turquoise hold up surprisingly well to water.
Diamine Shimmertastic Tropical Glow, Diamine Marine, and Noodler's Turquoise are probably closest to dictionary greenish blues strictly considered turquoise. Noodler's Turquoise is a little over saturated to have much fun with though.
Both Shimmertastic inks are really fabulous inks to write with and look incredible. The glitter really does not seem to hamper performance nor harm the pen. Amazing inks even if not shaken to get max glitter effect. Would love to see glitter free versions of these inks made available.
Some standouts at this time for me are Pelikan 4001 Turkis Turquoise for its beautiful color, versatility, sheen potential, and moderate water resistance. Lamy Turquoise is great too, good writing performance, some shading, and maybe some sheen. J. Herbin Bleu Pervenche is really nice too. I need more time to really study these inks....the differences between many are subtle.
Platinum Mix Free Aqua Blue is really pure cerulean - ish blue. It's also somewhat dilute and I really did not like it at first but now I kinda like it some. Levenger Blue Bahama looks quite nice but feathers some on everything but Tomoe River paper.
Let me know your thoughts.
