Ink on paper, paper on concrete, and exactly one red mark: the seal.

Hanko is an Obsidian theme named after the Japanese name seal. Almost everything is ink on paper; colour has a job or it stays away. The tones come from Sanzo Wada's A Dictionary of Color Combinations.

Hanko in light and dark mode

What it does

  • Paper on concrete. Notes sit on paper, everything around them on a concrete ground (light) or Wada's Black (dark).
  • Folders on a Wada plate. Top-level folders become solid pills in the colours of plate No. 279 (light) and No. 293 (dark). Raw Sienna is the anchor and always comes first. The colour follows the first character of the folder name, so it stays put while you scroll. Folders whose name contains "archive" turn grey.
  • The seal. A stamped name seal with uneven ink. It appears on notes you sign off with cssclasses: seal, on the empty tab and next to the vault name. Swap --hanko-siegel in a snippet to use your own mark.
  • Bold in the anchor colour. Bold text is Burnt Sienna in light mode and Raw Sienna in dark mode. Indigo, red, umber, plum, green and plain ink are available.
  • Readable everywhere. Every text and background pair reaches at least 4.5:1, in light and dark.
  • No network requests. Everything, including the seal, is embedded.
  • Light on the app. No :has() selectors, which can slow Obsidian down in large vaults.

Note building blocks

You write You get
cssclasses: seal the seal at the top right of the note
cssclasses: focus focus mode: only the paragraph with the cursor stays in full ink
cssclasses: daily-page, weekly-page, monthly-page the note title large, with a small label and a red dot above it
> [!days] with a list of links the days of a week as a row of cards
#evidence/strong, partial, contested, untestable, refuted evidence levels as pills: full circle, half circle, dashed ring, dotted ring, slashed ring
#status/active, waiting, someday, done status pills: full circle, clock, dotted ring, check
- [>] - [<] - [/] - [-] - [?] - [!] Bullet Journal task states: migrated, scheduled, in progress, cancelled (grey, never struck through), question, now
> [!recall], [!review], [!opinion], [!ask], [!correct], [!upfront], [!answer], [!exercise] role callouts; recall, upfront and exercise are raised cards because you answer them

Footnotes turn into a "Sources" list with hairlines and a red bar on the entry you jumped to.

Credits

  • Colours: Sanzo Wada, A Dictionary of Color Combinations (Seigensha), via the digital data set by Matt DesLauriers: mattdesl/dictionary-of-colour-combinations. Hex values are converted from the book's CMYK values, so printed colours look different.
  • Folder colours inspired by the Soft Paper theme.
