Being new to inks, I'm looking for a blue or turquoise ink for everyday use in demonstrator pens. I'd like the writing to be dark enough to be usable for everyday writing (notes, grading) but apart from that the two things I'd like to have are transparency and shading.
Noodler's Navajo Turquoise seems to be highly recommended, but I am wondering if people have other suggestions that I should compare or try out.
I understand that transparent blues are somewhat harder to come by than reds. I've been really enjoying Noodler's Dragon Napalm and would love to have a blue/turquoise ink with similar characteristics (although DN doesn't shade much).
