Colorverse #65 Mariner 4 belongs to Colorverse Season 5 and was included in the August Ink Flight box, the box is still available-you can find it here. Mariner 4 is a lovely dark navy blue with some pretty shading. It comes in a box set with a 65ml bottle of Mariner 4 and a 15ml bottle of Allan Hills.
Mariner 4 is a dark navy blue.
In large swabs on Tomoe River paper the ink has 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: 20 seconds
Water resistance: Low
Feathering: Low-there was some feathering in the flex nib on Rhodia and Leuchtturm.
Show through: Medium
On Staples 24 lb copy paper the ink feathered in the all nib sizes and had a lots of bleeding in the flex nib too.
I used an Edison Collier Blue Steel with a broad nib on Tomoe River paper. The ink had a slightly wet flow.
Overall, I love navy blue inks. There was a quite a bit of feathering and bleeding in the flex nib, so I would stick to standard nib sizes with this ink.
