Blue Black is a dark blue black that leans toward purple.
In large swabs on Tomoe River paper the ink looks less purple than it does in writing. There’s a tiny bit of red sheen.
Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.
Dry time: 20 seconds
Water resistance: Low
Show through: Medium
On Staples 24 lb copy paper the ink feathered in all nib sizes and had a little bit of bleeding.
I used a Pelikan M805 Vibrant Blue with a broad nib on Tomoe River paper. The ink had a wet flow.
Overall, I really enjoyed this ink. It has a lovely wet flow, some nice shading, and is at a great price point.
