A dark blue theme for VS Code based on the Ayu Mirage theme
A dark blue VS Code color theme ported from Ayu Mirage, also available for Sublime, Atom, and iTerm2. It's for developers who want a low-contrast, blue-toned alternative to the usual Dracula/One Dark palette and don't need anything more than a theme.
The README documents the exact hex values for every syntax and UI role instead of making you guess from the JSON, which makes it trivial to fork or tweak. It ships to both the VS Code Marketplace and Open VSX, so Cursor users aren't left out. Cross-editor support (Sublime, Atom, iTerm) means the same visual identity carries across your whole toolchain if you use more than one editor.
It's a single `themes/halcyon-color-theme.json` file with no tests and no way to verify the color-theme JSON stays valid as VS Code's theming API evolves, since there's no CI shown. The demo screenshot depends on a third-party icon theme (Material Icon Theme) with specific settings, so what you see in the README isn't what you get out of the box. No changelog or version history in the README itself, so you can't tell what changed between the one you installed a year ago and today's version without digging through tags.
