The author responded to this exact feedback in the comments: “No, the way medium's designers set things up, the text color follows the background color. The user (me) has no way of controlling that. The page was set lower than FFF because FFF is also much too bright. In light mode, Page luminance needs to be around 80 to no more than 90. I've been experimenting to see if there is a way to improve Medium's poor, inaccessible design choices. Unfortunately, attempting to use web inspector while in design mode, they crash the browser, so you have to publish each iteration to then go and inspect how the text colors end up. And it's actually worse than I imaginged. Medium actually makes the text worse when you choose a color other than FFF. As as I stated, FFF is much too bright. Ultimately, I think I am going to leave it in a dark mode, until I move my articles to a better site.”
