Black Pearl is an ultra-saturated quasi-sheener, boasting a rich black base that subtly reveals olive undertones at particular angles, then stretches toward a muted greenish-olive when applied in a thinner layer. Swatch is shown using a cotton swab on Tomoe River paper under fluorescent photography lighting.

The extraordinarily high saturation of Black Pearl may make some pens run on the drier side. Adjust your writing experience by adding Dilution Solution until it meets your flow and shading preferences. Expect variation in hue as you dilute. While the dye colorant components of this color are completely water-soluble, regular pen cleaning is recommended and may require extra effort.

For best results, wield Black Pearl with a medium point grade or broader nib.

A Chemistry Of Color

How It's Made

Our fountain pen ink formulas are developed in-house using fine colorant and a meticulously tuned vehicle. Every bottle reflects our commitment to performance, value, and creative exploration.

Formula Guide

We've compartmentalized our fountain pen ink recipes into four principal categories characterized by differentiating elements of the colorant component in the formula. A colorant is a dye or pigment that exhibits color. An ink vehicle is a series of chemicals used to transport colorant from storage reservoir to substrate (paper in our case). 

Keystone Formula inks are engineered using water-soluble dyes to produce a broad spectrum of colors with a variety of unique and desirable writing properties. Fitting the bill for a traditional fountain pen ink, this series by far the most popular. 

Delicate Formula inks are constructed with dyes selected for both performance and washability. Colors in this series will clean easily from most fabrics and surfaces with soap and water.

Everlasting Formula inks are compounded with pigmented colorants to produce highly water-resistant and archival properties on most papers.

Twinkle Formula inks are formulated using hybrid dye and pigment combinations to create a unique twinkling luster.

This hue is an Atomink Element building block for the color catalog.
