@Pookleblinky i haven't tried the NSFW button yet on the browser client at octodon.social, so i just experimented uploading a photo with a CW. It adds the NSFW in gray on the bar below. It does seem pretty visible once added, but I don't have visual issues beyond myopia. The fact that it's not there generally but only shows up once you upload a photo makes it easy to miss, tho.
