Anyway here is an issue about contrast on /about/more: https://github.com/tootsuite/mastodon/issues/4556
I'm not sure what part this is about exactly, but it's also about contrast somewhere on /about and /about/more: https://github.com/tootsuite/mastodon/pull/4567
And this is from April, about the whole theme, marked high priority: https://github.com/tootsuite/mastodon/issues/2280 (…including a link to a thread that I broke when I got anxious and deleted a toot where I used a wrong word, welp)
