When I first decided to try this ink it was out of stock. That got me the misty blue, which I like.
I now have the marine and I love it. For me it's just the right mix of blues and greens. It comes out with a nice intensity. In the Parker 45 it has a wonderful depth. In my Rialto it appears paler - intriguing how an ink can look so different in different pens. It's still a lovely colour though, just paler.
I can see this ink being in regular use. I would happily use it as an everyday colour
