Comment (by mcs):

 It seems that the error pages (about:netError) do not currently support a
 dark theme; at least on macOS, the colors used on that page do not change
 when in dark mode. Kathy and I cannot find a Bugzilla bug for that issue,
 but we think we should skip dark theme support for now.

 We tried using the `Grey 90 a80` color, but we need to avoid transparency.
 With transparency, the Browser/Network/Onionsite images show through the
 circles that surround the checkmark and (x) icons, and the Onionsite image
 is not a consistent color (apparently, some of the paths within the SVG
 overlap). Here is what it looks like with `Grey 70` (no transparency);
 Kathy and I think the result is close to your mockup:

 What do you think?
