The Sumis are Greywash dilutions based on number 6 True Pigment Black. Our sumis do not lighten during the healing phase, so caution is advised. Perfekt for shading.

#1 Sumi is 1/38 of the base black, meaning your base (#6 True Pigment Black) has been diluted with 1:37 parts of water. It contains four times less black compared to #2 Sumi.

#2 Sumi is 1/10 your base black (6 True Pigment Black) and is 3.5 times lighter than Sumi 3.

#3 Sumi is about 1/3 your base black (6 True Pigment Black) and is half lighter than Sumi 4.

#4 Sumi is an approx. 1:1 mixture of your base black (6 True Pigment Black) with water and is the darkest sumi. It's really very dark.
