Sumi

Ink on paper. A clean off-white ground, sumi-black ink, one indigo for the read-order mark and one vermilion seal for the single focal action — flat, calm, and printed, never muddy or cream.

Do
  • · Use the off-white paper as the ground and sumi ink for text.
  • · Reserve vermilion for the single focal action and the brand seal.
  • · Use indigo for the read-order tick, links, and the index.
  • · Keep semantic colours minor — never visually primary.
Don't
  • · Do not wash surfaces in cream or beige.
  • · Do not use gradients — colour is laid down as flat solid fields.
  • · Do not let vermilion become a workhorse colour.
  • · Do not place ink on indigo body text or low-contrast pairings.
