Phœnix Dark

There's a newer (BETTER!) version:

• Extension: https://marketplace.visualstudio.com/items?itemName=ncodefun.simple-focus-web
• Repo: https://github.com/ncodefun/simple-focus-web

VS Code theme with a minimal color palette, focused on values

Successor of the 'simple-focus' theme, with a more uniform color palette.

• All value types have the same vivid color;
• Colors for keywords / control characters / ponctuation etc. are muted;
• Optimised to work with the lit-html extension (js in html in js...).

HTML colors are different / contrasting with JS colors so when both languages are mixed in string template literals they are clearly distinct.

Javascript, Javascript + HTML (lit-html)

Almost there: note that in the last example the deepest div is not correctly highlighted as HTML, but as a normal string. Not sure whether this depends on the lit-html extension or the language services... Hopefully this should be adressed soon!
