Symbolic icons as far as I know only use one color so I don't think black and white fits the bill.

Just when I thought I'd finally gotten this right... Would be better to use #ffffff instead though? That seems to work better in my testing.

Not sure. Trying to research this through freedesktop but all there is is broken links! I might retract that 'request changes' due to lack of information. And I was wrong, not all symbolic icons are single color. Found some with warning signs overlaid and also some battery icons have color.

I would be inclined to add the outline to the white in black. But that's just me.

For reference:

With #000000:

With #ffffff:

I'm not sure why it differs to be honest here either. 😅

I'll leave this up to the team. I'll gladly do whatever the wisdom of the crowd desires.

Since my initial criticism is unfounded I can merge this. The icons are the same as in the main repo so all good.
