An amber CRT theme for VS Code. Warm phosphor, and no blue near the text.
An amber phosphor monitor, as a VS Code theme.
Before green won, plenty of terminals glowed amber, and people chose them for long sessions because warm light is easier on the eyes. This one keeps that: the ground is warm black, and amber carries the frequent tokens — functions, properties, ordinary identifiers — so the screen reads orange at a glance.
The sparks stay warm too, with one deliberate exception: types are teal, the complement of amber, so a type is never mistaken for a call. There is no blue anywhere near the text, which makes this the one to leave on late at night.

Comments, keywords, storage, this, parameters, annotations and attributes are the things you skim past or read as scaffolding. Slanting them separates them without spending another colour.
tool/build_themes.py refuses to write the theme if any syntax colour, UI label or terminal colour falls below 4.5:1 on its own background, or if two roles a reader must tell apart sit too close together. The lowest here is the comment colour at 5.52:1.
A theme cannot set your font — editor.fontFamily is a user setting. The italics are designed around Victor Mono, whose italic is cursive, but any monospace face with a real italic works:
"editor.fontFamily": "Victor Mono, JetBrains Mono, monospace",
"editor.fontSize": 15,
"editor.lineHeight": 1.7
Six themes, each a different screen or medium, built the same way: one palette, contrast measured at build time, nothing below 4.5:1.
