Themes
Plagx Paper (light)
Warm off-white background with dark ink text, for long writing sessions in daylight.

Plagx Ink (dark)
Soft dark background (not pure black) with warm headings and gentle accents.

Made for writing
- Readable prose: body text is high contrast; colour is kept for structure, so long paragraphs stay calm.
- Clear Markdown: headings, italics, bold, quotes, links, lists and inline code are each distinct, and Markdown punctuation (
#, *, >) is dimmed.
- LaTeX and BibTeX: sections,
\cite and \ref commands, citation keys, entry types and fields have their own colours.
- Accessible: all text colours meet WCAG AA contrast (4.5:1 or more) against the editor background.
- Gentle code colours: low-saturation strings, keywords and numbers that don't compete with your text.
Install
- Open Extensions (
Ctrl+Shift+X / Cmd+Shift+X) and search for Plagx Writer Theme.

Ctrl+Shift+P), run Preferences: Color Theme, and choose Plagx Paper or Plagx Ink.
