I dont think so.
I’m pretty sure Papirus-Dark is for use with dark themes … so they should contrast … and be … not dark … preferably something like … white.
The plugin also has similar icons to show the microphone level that is displayed in red only when microphone is live
The microphone-level icons in /usr/share/icons/hicolor/scalable/status/ are white so I suspect that colour change to red is possibly a client-side decoration thing?
(I don’t like the red microphone icon because it distracts from audio tools that have better, configurable status indicators for audio devices. But I replaced panel plugin with a launcher for pavucontrol --tab=1 long ago)
Papirus-Dark has single icons for speaker and microphone, but they are also white, so you may need to create a custom set of replacement icons in red
@cscs I was using a few Debian/Ubuntu Xfce distros in 2013 and they usually had xfce4-mixer plugin
I know papirus falls back on hicolor. Thats not what I am asking. It also inherits a couple other icon sets to fall back on in case of shortage of some icons.
I was originally talking about the color. Pulse audio status icon which was my initial concern seems to never change color to anything but white.
I have since cracked it up though. Here it is, all icons red:

But it is not papirus icons. Its a different icon pack.
With papirus, pulse audio is just white and thats the end of it. Try it yourself. Use green square as a replacement. Volume icons reside in 16x16/panel 22x22/panel 24x24/panel. You should notice it changing to square but of white color.
Papirus volume icon always gets whitened no matter what you replace it with.
