Usually, between 6 and 8, but when that question arose last year, I had 14. I try not to go too crazy to avoid spending too much time on cleaning. Right now, I have 9:
- Waterman Expert with J. Herbin Perle noire (my mainstay dye based black ink with Waterman’s black)
- Waterman Exception with J. Herbin 1670 Emeraude de Chivor (yes, I daily this ink)
- Waterman Allure with J. Herbin Bleu des profondeurs
- Pimio 916 EF (the red and gold one, fifth one, top row, first picture) with Noodler’s ink X-Feather black, diluted to 50% with distilled water
- HongDian 517D EF with Jinhao’s 5001 black, diluted to 60% (same for all the pens using this ink)
- Jinhao 85 EF (the right blue and gold from the first picture, bottom row) with the same batch of diluted Jinhao black
- Pilot Explorer M with the Jinhao black
- Wing Sung 601A (which is not pictured) with Ostrich 555 diluted to 50%
- Pilot Custom 74 F with Ostrich sheen Sea of Okinawa diluted to 80% (tiny bit less sheen, but way brighter on the page)
But I also have two drawers full of ink bottles and a big storage container that barely closes, with more inks and various converters and needle tipped bottles I use to refill cartridges and converters; last time I counted, probably in 2021 or thereabout, I had above different 30 inks in stock, and that was before I tried Chinese inks, and I bought quite a few of them. The Jinhao ones are pretty good across the board, except their brown that is kind of pink in the pens I tried it with, and Ostrich has crazy good stuff too, their sheen series in particular is amazing, because they’re not just cheap, but they’re usable, except the Glen of the sea, but this one is insane.
If you want to talk inks, I’ll be right there with you, even if I write mostly with black inks.
Also, even if it seems like a bit of a large collection, it’s not an expensive one, most of the good pens in my collection are single digit prices (at least in euros), while the most disappointing to me have been the expensive ones (mostly the Parker, Platinum and Pilot, as if the letter P was a bad omen).
Regarding your comment about number of inks compared to number of pens, please don’t take this as enticement to go buy more pens, but I think you could be depriving yourself of one aspect a diverse collection of pen can bestow upon you: how different one ink can look in different pens and how unpredictable that can be.
For instance, the Ostrich sheen Sea of Okinawa, it’s a bright blue with red sheen, nothing crazy, and it’s an actually good daily ink in my opinion, but I digress: in my Exception (rather broad for size medium nib and a very wet one), one could expect it to show more sheen and show darker than with something like the Custom 74 in F I have it in right now, but no, the result is the opposite of what I would have thought. It shows darker in the Pilot than the Waterman, and and the sheen is rather flat and uniform. It also shows very little shading. And that’s why I diluted it, to force it to show brighter in the thinner Pilot. The Waterman even shows some haloing, that has never shown in any other pen I have tried the ink in, most likely because it’s the broadest non stub nib I have.
So you’d think a broader nib should make it look brighter and sheen more, even if it’s a wetter one, at least I did, but I was wrong: I tried it in the Picasso (or Pimio, whichever name you prefer) 902 with the M nib, which happens to be close to the Waterman M. The shade of blue is rather close, a bit darker despite not being as wet, but the sheen isn’t, it’s flatter and shows less variation than.
And one that has been “crazier” is the Jinhao blue-black/black-blue/dark blue/deep blue (depending on whether you check the bottle, the box, official literature, in English or Chinese). This is an ink that I think was meant to mimic the Parker Quink blue black, but the color looks vastly different in different pens. In a Jinhao 35 EF for instance, it looks identical to the Quink. But in a Hero 1079 superfine, it looks like a warmer blue, not quite teal, more gray, almost like it gained an aged yellowish hue. In a Pimio 902 M, it looks like a darker, deeper blue, none of that grayish blue you’d expect from a blue-black. And that happens across the board on all paper types I have used them on.
So, what I’m trying to say is, I guess I care about inks too?

Now before I forget, for the future, I would recommend investigating test tubes: you can plug them to keep the ink from spilling or evaporating, shake them to mix, and use them to fill up your pens, keep them upright. They have two major drawbacks though: still can’t finish ink from them, and they don’t protect from light. Also, for this kind of fill, I find it easier to pull the feed out and fill from the section than mess with the piston.
Now, when you want to mix inks, you need to remember one important aspect of the human eye: it is twice as sensitive to green as it is to blue (give or take), and when you think about that, you can understand how blue our planet truly is, or how grey plants might actually be.
Also, mixing inks should be fine if you use inks from a same brand, because that’s basically what inks are: a mix. But it’s a good idea (so one I disregard of course) to not mix dye based with pigment based, because that’s when things go a little unstable, separate, or have odd reactions. Don’t get me wrong, you can get shifting hue from mixing two dye based inks from a single brand, but it’s nothing a good shake can’t fix, usually.
If you really want to start mixing inks, you should check out magnetic stirrers. And no, I’m genuinely not trying to be an enabler.
I don’t find your green and blue result to be that surprising: you mixed a green that’s pretty yellow, with a very dark blue that sheens red, so when you think about it, it sort of checks out.
What I find, maybe not funny per se, but intersting, is that I’m fairly confident we could find the resulting mixes in Herbin’s lineup. It’s hard to say for sure, but I think your purple might be their Poussière de lune, your orange could match their Rouille d’encre, your resulting light black seems close to their Gris galet, although your green… Lierre sauvage maybe?
Also, you don’t have to fill up your pen, you can also use it as a dip pen (provided it’s empty and clean).
And I’m with you on the distinctions: I have a bunch of black inks, but some of them are black, and some of them are… slightly darker black.
