A presentation illustrating the issue

Consider the attached single-slide presentation. It was originally created in Powerpoint, but the table was created in Impress.

* The text in the black-background column - is black.
* The text in the purple-background column - is black.
* The text in the transparent box in the title area is black, even though the underlying graphic is dark, night-colored even.

This, despite all text having been formatted in Automatic text color.

Reproducible from scratch with:

Text is shown in black, until you edit the text in the table cell.

You mean, not with my file? If so, can you give reproduction instructions?

Also, this is actually two-issues-in-one: Dark area, and transparent area over a dark background object. Which did you reproduce?
Comment 3 Rafael Lima 2022-06-15 20:49:50 UTC
When you click the black-cell in the table to edit the text, the text gets a white color. But when you exit the cell, then text becomes black again. This does not seem to be the correct behavior - BUG.

As for the text in the transparent box saying "Automatic for the people", I believe the result is expected, since the box itself is transparent, so it can't know what's beneath it to determine text color - NAB.

Confirmed with file. Tested with many versions. Before 4.4 all of the cells have blue colour.

Font color is currently calculated against Light Blue 2, see https://gerrit.libreoffice.org/c/core/+/157568 (reverted).

So, what that supposed to be a fix, and got reverted? Why?

Or - was it an unrelated patch? I don't quite understand.
