Walnut Ink

Walnut ink is a water-based, natural colorant made from walnut husks that can be used for drawing, painting, and lettering. It’s available in a variety of colors and can be used on porous surfaces to create earth tones. Walnut ink can have a sepia tone and is fade-resistant. It can also have watercolor-like properties, allowing for layering and lifting in darker washes.

Walnut ink comes in the form of walnut ink crystals or bottles of ink that are ready for use.
