Diamine has been in the ink business since 1864, and if their website is any indicator, they seem to take exactly the right approach to their business: serious, but with a sense of fun. I am a big fan of Diamine, as their inks are generally willing to get along with any pen they’re put in. They offer a variety of bottle sizes, none of which have the geometric problems which afflict Herbin, and some of which are a pleasingly vintage shape which I can’t decide is more Victorian or Art Deco.
Examples (note– I’ve not calibrated my scanner, so these are mere approximations of the true colour):
China Blue: A pale blue, perhaps slightly less deep than that found in Delft china, but certainly in that area. I like it because, while it is the colour some makers’ standard blue inks eventually fade to (a rather rude trick), it is at least honest about its paleness and doesn’t get paler over time.
Majestic Blue: A highly saturated ink, which is a bit of a rarity for Diamine, it is all the name suggests; a deep, impressive blue. There is so much dye in it that a reddish sheen is frequently observed on the page. It is not at all water-resistant, and acts as a bit of a booby-trap for those who wet their fingers to turn a page. It’s a colour I love to look at, but the challenge of flushing it out of a pen is such that I rarely resort to it. I recommend it for vintage pens with simple feeds, as the cleaning is less of a penance.
Royal Blue: A quite bright blue, moreso than most other makers’ version of this colour.
Steel Blue: A fine example of the difficulty in declaring the end of blue and the start of green. In some concentrations, and on some papers, the greenness of it is unavoidable. Ironically, it’s a colour that modern Quink blue-black will turn over time on many papers.
Prussian Blue: I might, if rumours about the unavailability of Pelikan blue-black prove founded, recommend this as a replacement. It’s a slightly greyish blue, although unlike that Pelikan colour it is definitely a blue in all uses. Also like the Pelikan ink, it is very dry; I’ve got several pens that is hardly comes out of.
Bilberry: I’m not quite sure whether to call this a very blue purple, or a rather purple blue. It is somewhat less saturated than Majestic Blue, and also rather more freedom of flow, but has a similar visual richness on the page.
Amazing Amythest: A somewhat bluish purple, which generally comes out looking very like Herbin’s Poussiere de Lune, but which can with some paper/pen combinations take on what my wife describes as a “grape koolaid” aspect.
Imperial Purple: Certainly not a troublemaker like Majestic Blue; a good middle-of-the-road purple, perhaps even the sort one might find on the edging of a toga.
Syrah: A much more successful attempt than Claret (see below) to get the look of a good red wine down on a piece of paper. A bit of a challenge when time to flush the pen comes around.
Emerald Green: More of an idealized than an actual pursuit of the idea of emerald (see Chelpark for an example on the other side of that fence), but based on pictures I’ve seen it does look rather like Ireland.
Evergreen: An extremely mellow, woodsy green. It’s not quite a green-black.
Dark Brown: Actually rather ruddy; I’d be more inclined to call it Dark Rust.
Rustic Brown: Darker than Dark Brown, although still somewhat red of tone. A decent sort of chocolate colour.
Ochre: I’m tempted to call this a “standard brown”; it is definitely a darker brown than Dark Brown, and is quite earthy. Update— flushing this ink out of a pen produced a remarkable amount of red; you might want to pause and consider before putting this ink into a pen given to taking on a stain.
Oxblood: Very similar to Noodler’s red-black, but a slightly richer tone. It’s also very similar to Monaco Red and Syrah, being darker than the one and more brown where the other has its purple elements.
Monaco Red: I hope I’m not the only one who has to work to see the difference between this and Rustic Brown. This colour was apparently a special commission undertaken at the behest of the Grimaldis.
Classic Red: True to its name, a very old-school red ink. Not as profound as Skrip’s version, but bright enough.
Claret: Hot pink, really. It does look somewhat wine-like in the bottle, but the name is slightly misleading when it’s on the page.
Flamingo Pink: Slightly brighter than most flamingos you’ll have seen, but not an offensively bright pink.
