These are my takes on alternate Sync logos for Lemmy (I made that rat from a while ago)
The logo for Sync is so tied to Reddit for me personally, that it was hard to think of ways to translate it to Lemmy (or the Fediverse overall).
Orange and Blue are signature colours for Reddit, but Lemmy doesnt necessarily have a colour scheme. Nor should it. that's up to the instance operators to choose, making their community unique.
I also like the general Fediverse pentagon logo, but it can look quite busy...
I did what I could. I'm an average designer at best ยฏ_(ใ)_/ยฏ
These look really great. Well done on iterating while still keeping the "sync feel". I think the default logo should stay the reversed colours of the sync for Reddit logo but I would love to see some of these as alternate icons!
Only little note is that the bottom left should have 1 more purple leg (the one going straight up should be purple).
Re: your note, your change would make it the same as the middle. I think it's meant to show overlap with the green being the first layer.
I'm really not sure how I missed that. I'll leave my original comment as is but you're definitely right.
