I built Vibe in Color for myself after discovering that importing themes one by one was an inefficient way to learn that chat looked fine and the diff was unreadable. It’s a native Mac app for browsing 200 original light and dark Codex themes, grouped into ten work vibes. It previews chat, code, diffs and fonts already installed on your Mac, then passes the selected theme to Codex’s built-in importer. It’s free, Apple-notarized and runs locally with no account, analytics or network access. I made it for my own setup and released it because this seems like exactly the kind of oddly specific problem other developers may also have. Feedback on readability, missing palette families and whether the vibe grouping is useful would be genuinely helpful. Yes, 200 is excessive. That is also the useful part.
