Kaweco Paradise Blue and Caran d’Ache Caribbean Sea

I have previously posted here about four Kaweco inks that look similar to four corresponding Caran d’Ache inks. Though none is an exact match, they are fairly close in color.


All of the foregoing are current inks. But my friend Chris read that post and had a great idea: she wondered whether Kaweco’s turquoise ink might prove to be close to an older, now discontinued, Caran d’Ache ink — Caribbean Sea.

Here’s some quick history: Caran d’Ache previously offered nine fountain pen inks in the Colors of the Earth collection, including Caribbean Sea. In 2013, Caran d’Ache replaced the Colors of the Earth with a new line of 12 inks called the Chromatics collection.

The turquoise in the Chromatics line is called Hypnotic Turquoise, and it is quite different than the old Caribbean Sea.

But Kaweco Paradise Blue is a more blue-green ink, and so is closer to Caribbean Sea, as Chris noticed.

I happened to have a tiny amount of Caribbean Sea left over. So I bought a bottle of Kaweco Paradise Blue to test the two together. Meanwhile, Chris did the same.

Our conclusion is that Kaweco Paradise Blue and Caran d’Ache Caribbean Sea are very close, though not the same. My sample of Caran d’Ache Caribbean Sea has more blue, and my Kaweco Paradise Blue has more green.

When comparing the two inks, I did some paper towel chromatography. On the left is Caran d’Ache Caribbean Sea. On the right is Kaweco Paradise Blue.

Here are some writing samples, with each ink in a Lamy Safari with medium nib. In each pair of lines, Caribbean Sea is first and Paradise Blue is second.


Here, Caribbean Sea is on the left and Paradise Blue is on the right.


The scribbles have more density, so the color difference may be easier to perceive.


Paradise Blue does have more green in the mixture. But the more you write with the inks, and the more you look at them on the page, the more Paradise Blue seems like a possible replacement. It’s worth testing, at least.

When I tested them, it turned out that I actually preferred Paradise Blue. So I am very glad that Chris had that inspiration.

  1. I just got a bottle of Kaweco Paradise Blue after going back and forth on if i actually wanted it for a long time. After I wasn’t able to get the Chicago Pen Show exclusive Lake Michigan Summer (I think that’s what it’s called?), I looked for similar colors, and this seemed close. Do you think these two are close? Or is there something else you think is more similar?

    1. !. I think it is similar to Kaweco Paradise Blue, with Paradise Blue slightly more blue. I’ve still got Lake Michigan Summer inked, and I’ll ink up Paradise Blue in another Safari or Al-Star to compare.

      2. Another similar ink is Diamine Steel Blue, with two caveats. First, I’m not sure that Diamine hasn’t tweaked the formula for Steel Blue since I bought mine years ago, because my friend Chris seems to get a different vibe from her Steel Blue. Second, I have to admit that I never really took to Steel Blue. Something puts me off that ink when I use it a lot. (Whereas Paradise Blue and Lake Michigan Summer I liked initially and continue to like.) YMMV.

      3. I just saw on Instagram that Papier Plume is making another batch of both Ivy 108 and Lake Michigan Summer, in response to requests. So if you email them, or maybe just check their website, you might be able to actually order it once again. If any of the New Orleans Collection, just re-released, appeal and are still available, I really like those, too. Okay, it may seem “what inks don’t I like” but I’m actually kind of a tough grader. 🙂


      1. I really like Diamine-Steel Blue, and have it. I love the look of that Lake Michigan Summer, and would love to try it one day. Maybe there will be enough demand to bring it into their regular line up. If it is too close to the Steel Blue though, I won’t need it. I think it is more blue than Steel Blue, but I might be wrong about that.

  2. This is the first time I’ve seen this blog entry. I loved it. I have tried Paradise Blue, and I really like that ink a lot. Sadly I never got to try Caribbean Sea, although I know people rave about it. I am glad you did those comparisons. I also love Palm Green, and it does look fairly close to Vibrant Green from Caran d’ Ache. (from the picture) I have both of the Kaweco colors mentioned in cartridges. I did try one of the Caran d’Ache samples though…Infra Red. I was looking for a reddish orange, but it wasn’t quite what I was looking for.
