A good theme is almost nothing. It is a room with the right light in it, a chair that you forget you are sitting in. It clears the table so that thinking has somewhere to happen.
Nous is built for the long read — the essay begun in the morning, the footnote chased down before lunch, the quiet half-hour with an old book that you keep returning to. It is a theme for Obsidian, for Typora, and for the small websites where people still write in paragraphs. It is not a theme for dashboards or for screens that need to shout.
The name comes from the Greek. To the ancients, νοῦς was the faculty of the mind that simply sees — the part that recognizes a truth before it has finished proving it. That is the kind of attention this theme is made for. Not the scroll, but the pause.
Its colors come from a single afternoon: the limestone of a half-ruined temple, warmed by the sun; the small blue of the sea through the columns; the olive that grows indifferent to history on the hillside. Nothing saturated, nothing that wants to be looked at before the words are.
Its typography is drawn from the printed book. Headings in Cormorant Garamond, set wide and unhurried. Body in EB Garamond, old-style figures, real italics, ligatures on. A monospace (JetBrains Mono) only when code demands it — and then set a full size down, so it knows it is a guest. Greek sits in GFS Didot, upright and calm.
What you will find here is a system of small decisions, all in the same direction: toward the reader, and away from the interface. If the theme is doing its work, you will not notice it after the first paragraph. You will notice only that you kept reading.
