Inkstand colour is the series of base inks used at Inkstand, our colour creation service where you can design your own fountain pen ink colours. These 14 blendable shades are also available as a range of individual bottles, so that you can enjoy the creative experience at home.

Complementing these inks are our two ink additives: Pearlescent solution and Diluting solution. In this guide, we’ll show you how to use these companion products to get the most out of your explorations with colour.

Diluting solution
The diluting solution lets you adjust the tone of your ink to make it brighter, lighter or softer. A small amount brightens the colour, while adding more creates a lighter, softer finish. From the pastel pink of cherry blossom petals to the clear blue of a cloudless sky, this solution helps you create your desired colour.

Our Ink mixing kit, which includes five mini droppers and three cups, is the perfect companion for your colour experiments.

Start by mixing inks from the Inkstand colour range, then gradually add the diluting solution. Stir with the tip of the dropper tip and test as you go until the colour is just right.



Once you’re happy with the result, try it in your pen — you’ll enjoy a softer, more delicate hue that looks more like a watercolour than regular fountain pen ink.

Tips for colour testing
Some pens, particularly those with fine nibs, naturally produce lighter colours on the page. While the diluting solution can be used in any amount, keep in mind that diluting the ink too much may result in a fainter colour when used in your pen. Testing the ink using a similar line width to the pen you plan you use will give you the best indication of the final colour.

Pearlescent solution
This ink additive gives your ink a delicate shimmer, perfect for accentuating your everyday colours. It’s equally striking on black paper as it is on white paper.

To use, simply add it to your mixed base colour, just like the diluting solution. As the pearlescent particles tend to separate easily, be sure to stir thoroughly with each addition.


Create your perfect shimmer by gradually adding the solution, testing as you go. For optimal writing experience, avoid adding more than the original amount of base ink.


The shimmer appearance varies depending on the amount of pearlescent solution and the ink colours used, so feel free to experiment with the ratio to find what works best. It can also be combined with the diluting solution to create a soft, pale pearlescent ink.

Before using the pearlescent solution
- The pearlescent solution is designed for dip pen use only. Avoid use with fountain pens and rollerball pens, as it may cause clogging.
- Shake the bottle well before use to distribute the pearlescent particles that may have settled at the bottom.

Together with the Inkstand colour range, our diluting and pearlescent solutions open up a world of possibilities for ink creation. Whether you’re writing or illustrating, enjoy endless expressions with these two unique additions.
