Diamine Lilac Night is part of the 2017 installment of the 150th Anniversary collection. I purchased my sample from Vanness Pens.
Lilac Night is a dark purple with shading. It doesn't quite look like lilac to me, but it is a nice purple.
There is just a little bit of sheen that shows through in large swabs.
Let's look at how it behaves on fountain pen friendly paper first (Rhodia, Tomoe River, and Leuchtturm).
Dry time: 30 seconds
Water resistance: Medium-this really surprised me. Some of the blue ink washes away, but the purple stays pretty well.
Show through: Medium
On non-fountain pen friendly paper (Moleskine), there is a bit of feathering and bleeding. I wouldn't recommend this ink for cheap paper.
I started out with a Pilot 912 FA and then switched to a broad Vanishing Point. I used Tomoe River paper, and didn't really have any issues.
Overall, it's well behaved and a nice color. I like that it has some shading and a tiny bit of sheen.
