Kiln
A warm VS Code theme based on ceramic glazes. It comes in two variants, with a file-icon pack drawn in the same palette.
- Kiln Tenmoku: dark. Iron-black backgrounds with bright glaze colours for code.
- Kiln Bisque: light. Unglazed-clay paper, with the glaze colours darkened for daylight.
- Kiln Glyphs: 81 file and folder icons, each in a dark and a light version. Covers 121 extensions and 72 special file names.
Every syntax colour has at least a 4.5:1 contrast ratio against its editor background (WCAG AA).

Install
- Install Kiln Theme from the Extensions view, then pick Kiln Tenmoku or Kiln Bisque with ⌘K ⌘T (Ctrl+K Ctrl+T on Windows and Linux).
- Choose Kiln Glyphs under Preferences → File Icon Theme.
- Install the font. On macOS:
brew install --cask font-recursive-code. On Windows and Linux, download it from recursive.design.
- Set
"editor.fontFamily": "'Rec Mono Duotone', monospace" in your settings.
To switch between Tenmoku and Bisque with your system appearance:
"window.autoDetectColorScheme": true,
"workbench.preferredDarkColorTheme": "Kiln Tenmoku",
"workbench.preferredLightColorTheme": "Kiln Bisque"
Font
Rec Mono Duotone, from Arrow Type's Recursive family (SIL Open Font License). Code is set in the linear roman. Comments, control-flow keywords and parameters use the casual cursive italic. The theme puts those tokens in italic on purpose.
Customising
All colours come from scripts/palette.mjs. Edit that file, then run:
npm run package
This rebuilds both themes, the icon pack and kiln-theme.vsix.
