Diamine Carnation is part of the Diamine Flowers Set, Cult Pens sells the bottles individually. The ink comes in 30ml bottles.
Carnation is a pretty bubblegum pink.
In large swabs there is just a little bit of shading.
Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.
Dry time: 30 seconds
Water resistance: Low
Show through: Medium
On Staples 24 lb copy paper there was feathering and just a little bit of bleeding, mainly in the flex nib.
Overall, I like the color and how bright it is, but it doesn't have much shading. It's well behaved, and has a nice flow.
