3 Oysters Black Moss — Dark Green Shading Illustration Ink
A black that isn't quite black
Black Moss reads as a very dark green-black when laid down — on first sight you might mistake it for a standard black. Look more carefully as it dries. The pooled areas in curves and stroke endings reveal a deep green undertone. The lighter parts of a stroke show a warmer, slightly olive tone. The result is a black that has depth without announcing itself as a colour.
For illustrators who work in linework — particularly those who want their black ink to feel atmospheric rather than graphic — Black Moss is one of the most useful inks in the range. It pairs naturally with the warmer earth-tone inks in the Colour & Drawing section for illustration work that wants tonal range without obvious colour.
About 3 Oysters
3 Oysters is based in Seoul, South Korea. The brand name comes from the idea of the three tools of writing: pen, ink, and paper — three things that seem ordinary until you understand what they do together. Their Delicious Series inks take their names from Korean food and fashion, and each arrives in a 38ml heavy glass bottle with a distinctive faceted edge designed so the bottle leans at an angle to capture the last drops. We stock eleven colours from their range, chosen specifically for illustration use.
