Describe the feature or problem you'd like to solve
The github color mode follows the reported OS or terminal appearance, and there's no way to pin it. I want the GitHub palette in dark, permanently, while macOS stays in Light during the day. That combination isn't reachable today.
Proposed solution
Requested change: accept an explicit variant, such as /theme github-dark and /theme github-light , with plain github keeping today's automatic behavior. A separate "follow OS appearance" toggle would work equally well.
Example prompts or workflows
No response
Additional context
What happens now: my terminal profile is black, but macOS switches to Light on its daytime schedule. Every running CLI session flips to a white background at once, usually noticed on wake from sleep. Restarting fixes it, because startup derives colors from the terminal's actual palette instead.
The relevant behavior, from app.js in 1.0.81-9:
if (n() === "github") {
let c = l === "light" ? { bg: cse, fg: Pq } // #ffffff
: { bg: lse, fg: Rq }; // #0D1117
t(d => d && { ...d, ...c }); return
}
github is the only mode that hard-follows the light/dark signal. Every other mode re-queries the terminal's real colors, so those stay dark. That makes the palette choice and the follow-the-OS behavior one setting when they're really two.
Worth noting the workaround isn't obvious. Setting a fixed theme in the terminal emulator can work, since the terminal's DECSET 996/997 reply takes priority over macOS appearance, but that changes the emulator's own window chrome as a side effect. There's no fix available from within the CLI.
