ah 0.1.424 (macOS, build 12709a7e-dirty, stable channel / insiders tier) · adom/core 4.15.3 · adom/adom-theme 2.3.9 · adom-vscode 1.1.113

What I did: Updated to Hydrogen 0.1.424 on macOS. In Settings → Adom Hydrogen → Appearance, the Color Scheme is set to Adom Studio Dark and shows "Applied".

Expected: The VS Code pane picks up the Adom Studio Dark scheme along with the rest of the app, as the Appearance page says it should ("applied to Adom Hydrogen and the editor together").

What happened: Hydrogen's chrome and Settings window are dark, but the VS Code pane stays light (see screenshot).

Likely cause (checked from inside the workspace):

workbench.colorTheme (global) = "Adom Studio Dark", so Hydrogen wrote the setting.
No installed extension contributes a theme named "Adom Studio Dark". Installed: adom.adom-vscode-1.1.113, adom.adom-agent-bar-0.2.7, Claude Code, Codex, Kimi, Antigravity. The Adom VS Code theme pack isn't among them.
Because the theme ID doesn't resolve, VS Code falls back to its light default. (Other values: workbench.preferredDarkColorTheme = "Dark 2026", window.autoDetectColorScheme = false.)

So the new version seems to set the Adom theme name without installing or shipping the theme pack in the workspace on macOS. It may be related to the closed adom/hydrogen#22 (light theme after update-restart), but the cause here looks different.

Still happening after updating to ah 0.1.428 (macOS).

workbench.colorTheme is now "Adom Studio" (it was "Adom Studio Dark" on 0.1.424), so Hydrogen is writing the scheme name.
code-server still has no extension that provides an Adom theme. The installed Adom extensions are adom.adom-agent-bar-0.2.8 and adom.adom-vscode-1.1.113, and neither has one.
The VS Code pane still falls back to light.

@kyle can you take a look? This still happens on ah 0.1.428 (details above).

Confirmed root cause and workaround: the adom.adom-theme VS Code pack was not installed. Re-running adom-wiki pkg install adom/adom-theme did not install it (already-installed packages skip install.sh). Running adom_modules/adom/adom-theme/install.sh by hand installed pack v2.3.7 through code-server and registered it in extensions.json. After that, all five Adom themes showed up, and workbench.colorTheme = "Adom Studio" applied live. So Hydrogen 0.1.42x, or its setup step, does not deliver the theme pack on macOS.
