Our Ultra Dark Brown Ink is very heavily pigmented and made with the same binder as the original so it can be mixed with our original Tom Norton Drawing Ink without changing its working properties. It shares the unique watercolor characteristics of our original ink and can be lightened and lifted as needed. When used straight from the bottle it is a very intense dark brown that adds a rich “punch” of color to your drawings. Most artists will flow between the original ink and Ultra Dark Brown to create a wide range of light and dark browns.
