The app lacks a proper Solarized theme.
There is selenized, but the background seems to be a brighter hue than the standard Solarized, so the app stands out from my other applications (not in a good way).

No source file or test is named. Start by locating the existing selenized theme and comparing it with the standard Solarized palette; done means the desktop app offers a Solarized theme whose background matches that palette, including on the /chat path.
