It was up to us but he recommended to fill the aircraf's logbook with "blue" ink.
And when I asked why, his only answer was:
"You can see the difference between entries and black lines of the logbook"
I guess he was reffering the possiblility of having someone writting too wide and overlapping lines.
You laugh but as someone who frequently does paperwork while flying I sometimes find it difficult to stay within the lines perfectly. And I do find that since the lines are black, blue ink is easier to read.
