Not an important thing of course just that I was unable to use gconfig on my system with a theme dark is set like [1] and this turns it into [2] without noticable change to the light theme. I had hit this minor issue also in the past but decided to fix it this time. This isn't the best possible approach as now we have we have a GdkColor -> gchar * -> GdkColor round trip, yet wanted to keep the change small and maybe go for a larger change later if it worths it. Hope you find it useful also. [1]: https://i.imgur.com/MJfIkup.png [2]: https://i.imgur.com/lgvod9V.png
