Yup, that's because "fill:#2e3436" is hardcoded in the SVG files.
Removing that bit makes Emacs use the foreground color for the default
face.

I don't know if we want to do that (it's sort of a nuclear solution),
and/or introduce a face to let themes control this color; it's true that
as things stand, these buttons are not very visible for dark themes.

(I still find them more appropriate for UI elements than glyphs that
change depending on fontsets, FWIW)
