Color is Alive - Walnut & Oak Ink

This piece is a 1/1 artwork made with natural ink and part of the artist's project Color is Alive, a reflection on colors as living matter.
The unique brow hue is obtained from walnut hulls, foraged by Greta Desirèe Facchinato in The Hague. The deep black hue is obtained following one of the most ancient techniques to make black, by using oak galls foraged in The Netherlands and UK by the artist.
