High-quality ones, used by a couple of artists and a draughtsman my parents knew, were blue: Staedtler Mars Lumographs, again made then in the UK, but now only made in Germany. Still an even better pencil than the Noris.
I remember Berol "Handwriting" pens, red with a white nib that produced blue ink, but never liked them or used them much. Berol had colouring pencils sewn up when I was in school.
