Description

I've use the oficial Fedora logo, but to display in only black-white, I've removed brighter line inside the logo, so it is simple to see is the 'f' like the Fedora. If I colorized this line white, it would be infinity sign.

Color was got from official Fedora logo guidline #294172

I could've sworn there was an existing discussion on the Fedora logo, but I can't find it for the life of me. Must be something I've imagined ¯\_(ツ)_/¯

Monochromization of this one is difficult. There are a couple different solutions to this in other icon packages (e.g. FontAwesome uses hashing, while font-logos use the solution also chosen in this PR). There's some good discussion on Fedora's own issue, including a suggestion that might work with the current logo (although to match the current logo this would need both ends of the "f" marked):

It should also be noted that they have a new logo which was approved 2 months ago. They have not yet started using it, so we should stick with the old logo (the one in this PR) until they do.

I am ok with the monochromization this PR currently has. Will wait for another maintainer (@davidklebanoff @ericcornelissen) before merging.

I personally feel like the approach taken by @hylickipiotr is more recognizable than the one shown in @birjolaxew comment (but I'm not super familiar with the logo), so I went ahead and merged it.

If anyone disagrees they can continue a discussion in this thread or open a separate issue 🙂

Anyway, thanks @hylickipiotr for adding this icon to the collection 🎊
