My thanks to Louisa for the ink sample.
Graf von Faber-Castell Midnight Blue is very much traditional blue black ink, rather a dark blue with a strong grey undertone. It shades easily and rather wet for a Graf von Faber-Castell ink. That’s really unexpected. This is a suitable colour for corporate use in terms of its colour. Graf von Faber-Castell Midnight Blue is a step above a standard blue or black ink because it’s not boring or devoid of shading.
