Its what it says on the box
Most of the papers I like to use are somewhat cream colored, which makes this ink indistinguishable from black unless you peer very close under good light. I was hoping for something a bit more green, but not the ink's fault. The Noodler's inks I've used all seem to flow well, clean out reasonably well, and haven't feathered much even on cheap paper. They are saturated and will show/bleed through thin paper, no question.
