Black v Blue Ink

[JBarry]

During my enforced idleness, I have noticed that fountain pen reviewers on Youtube seem to prefer showing writing samples with blue ink.
FPs aside, do your pen customers and gift recipients prefer a certain color ink refill over others?

When I was on the circuit and selling pens I usually gave the customer a choice and the most chose black. I prefer black myself.

Although I don't use fountain pens, I got in the habit of using blue ink in all of my rollerballs (everyday carries). Years ago when the quality of photocopiers improved to the point where it was difficult to distinguish between the original and the copy, I started signing with blue ink. After retirement the habit just stuck. - Dave

Many businesses require blue ink for documents. This distinguishes the writing from a black photocopy.

Many of my fountain pen customers prefer to find an ink that pairs nicely with the pen materials.
