@dansup From a designer's perspective, none of them are actually very good (technically speaking). Start from black and do colouring later. It should be legible as a favicon, as well as (already mentioned) near other social icons. A good logo needs to be able to work on different media; digital, print etc. I would suggest choosing a single colour as it makes creating a brand easier and more distinct. For me, these logos seem generic.

@dansup ooo please have a selection people can choose from! I love the pink ones of the top row but it would be fun to see everyone have the ones they like best. Maybe a poll?

@dansup I like the pixel one because it matches the name and the product.
Less keen on rainbow iris(es) that are to close tot the beach ball of death on macOS.

@dansup right on the first row or third

@dansup
All the three last ones on the third row are nice.

@dansup

If you're asking for opinions... Disclaimer, I might not even use Pixelfed (but maybe this is somehow useful still).

1st row: none

2nd row: nice, but none

3rd row: good, I vote for all but especially 5 and 6 (last two from left-to-right)

4th row: none

@dansup my graphic designer girlfriend and I both like third row rightmost the best, and the third row in general significantly more than the other rows.

@dansup the pixelated one (at the end of the third row) makes the most sense for sure 💯
