Diamine Damson is a dusty purple that reminds me very much of Rohrer and Klingner Scabiosa. Diamine Damson has much more blue to it while Scabiosa is much redder. The muted tones of Damson reminds me very much of a musty old library filled with tomes of knowledge. I enjoy the shading that Diamine Damson offers. This is fast becoming one of my stapble inks.
