Is this an Adwaita-ism? What happens if the theme doesn't have a theme_base_color? Will the GdkRGBA contain uninitialized memory? Do we need a fallback?

Good question. It is listed as a public color, and elementary also has it (I tested on that one too specifically). But worth to double-check, agree.
Comment 6 Michael Catanzaro 2019-06-21 07:22:27 PDT
Better add a fallback if there's any possibility the GdkRGBA could be uninitialized.

Yeah, agree. Realistically, `win32` theme may be missing it.
