I'm confused... has the meaning of "invert" changed since I last looked? Because the bar chart given as an example on the page isn't actually inverted (the color of the bars and as far as I can see also the text stay the same, only the background changes from light to dark). So, additionally to this API, you need another model that does the actual "inversion"? Or just good old editing?

EDIT: from another comment - actually "inverting" seems to refer to doing

    hue-rotate(180deg) invert()

...which (if I read it correctly) inverts the hue of colored areas before applying the actual inversion in order to keep the colors the same (more or less - see also https://stackoverflow.com/questions/65344006/why-does-filter...) ? Not a frontend developer, so I wasn't familiar with this trick until now. TIL...
