This is a deep dark brown shading verging on black on the finer nib sizes. Personally, I have never been a fan of brown inks but Ebony Brown is growing on me. Maybe it is because of its dark tones and not being a blend of red and brown. Colour aisde, this is a well behaved ink, saturrated but easier than Noodler's ink to use with mudging. However, I found ink clots in the Pilot Prera which was previously inked up with Ebony Brown. The pen hadn't been left sitting around for months. This is the first time this has ever happened. The inks has no problems with my TWSBI Mini though, a fluke?
