What is shading fountain pen ink?Updated a year ago

Fountain pen inks can have varying degrees of “shading.” This is the ink’s ability to show depth of color. Inks like Serenity Blue shade so you can see a darkening value scale within each line stroke.

Then, you have a multi-chromatic shading ink like Sailor Manyo Haha, which shades in both value and color. The lighter saturation of the ink shows dramatic color separation. Is this ink a green? Blue? Pink? It can be all of the above!

High-shading and multi-chromatic shading inks tend to be lighter in saturation and might be a little on the drier side in terms of flow.
