Solid Ink Onyx is built for black & grey control. It is described as the darkest of the opaques, almost black, making it essential for shading and creating black-and-grey tones.
This helps solve the problem of shadows looking washed out or inconsistent. Onyx gives you a deep, opaque endpoint so your dark zones stay rich without jumping straight to full black.
