Just as an example. This post
has already been published but it may give you an idea what’s going on.
Even if I’d select a different color for the headline (As Far as One Can Tell, etc), say red, on this page, once I’d update it and send it, it’d still show the headline in blue.
So, my palette of colors is definitely not working.
The problem happens with every post, of course, so it’s not that I’m trying to modify one particular text.
And I can’t stress this enough, I used to have the ability to choose the color for each headline according what I wanted, and it’d show that color once the post would be sent. So something happened last year, perhaps with one of the systemic updates, that made me lose that ability.
