The default icon is unremarkable, so I made one in a few different colors. Would you be interested in using any of these?
These are quite nice, thanks! I especially like the bottom-middle one.
Would it be possible to provide the icon in a vector format, ideally .svg?
Sure, I can do that.
The previous site won't take .svg files, so I'm uploading the icons to https://upload.disroot.org. They will be available for 30 days.
