I've posted before about the lovely De Atramentis Document Inks, created in Germany in 2014. These were a game changer when they first came out and I still love sketching with them. Mostly I use the Brown, various variations of Grey, and the Black, but I have also made a lovely burnt sienna ink, a raw sienna ink and some fun oranges and greens to draw with over the years.
Here are my previous posts.
Mixing Document Inks November 2014, updated January 2015, which shows a number of two-colour and a few three-colour mixes, and their ratios.
De Atramentis Inks - Mixing Document Greys November 2014, updated January 2015. This was in answer to a question about how to mix greys using other colours. I tend to make them with Blue and Brown.

De Atramentis Document Ink Mixes - Magenta, Blue and Yellow December 2014, update January 2015. This explores many three-colour mixes using the Blue rather than Cyan as the primary blue.

Documented Inks Revisited October 2018 which shows the inks mixed with Black and with White.
Over the years, the colour range has expanded and the bottles have changed size from 35ml to 50ml. The current bottles are larger rounded bottles but will shortly change to elegant square bottles with larger lids. I'll update with a photo once these are available.
The current range as shown on the De Atramentis website shows 17 colours. They are now called 'Artist Inks' but have the same properties as the original 'Document Inks'. They are nano-pigmented, waterproof and lightfast mixable inks designed for fountain pens.
|De Atramentis Artist Inks - White, Yellow, Orange, Red, Dark Red, Magenta.
|De Atramentis Artist Inks - Violet, Blue, Dark Blue, Cyan, Turquoise, Dark Green.
|De Atramentis Artist Inks - Green, Brown, Sepia, Grey, Black.
There is also a thinner available called Artist Ink Thinner so you can dilute the colours without changing the properties.
The colours are the same as the original Document colours, apart from the Green, which is now brighter. The current Dark Green is similar to the original Document Green I used for my mixing experiments.
Treat the Blue as an ultramarine or warm blue for mixing purposes. Treat the Cyan as a phthalo or cool blue for mixing. The Red is the warm red and the Magenta is the cool red for mixing purposes. I still love the colours you can create exploring the triad of Blue, Magenta and Yellow.
There are many more pigmented inks available now than there were when these were first released, which is terrific for artists who want to sketch with colourful waterproof inks in our fountain pens. I've explored many of them in this post but have stuck with the De Atramentis inks in my own pens.
Disclosure: I was kindly sent this range of inks by the manufacturer, but all opinions are my own.
