Does as advertised, but also messes up text colors.

Affects the menu bar with some customization for document background, but completely breaks outlines, summaries, and side panels by leaving the background unchangeably white with light gray font that's not readable. A good try for reading the doc, but otherwise unusable.

It works on a greyscale. Text colors do not appear. I cannot recommend this.

Works, but cursor color doesn't change, making it hard to see
