9.4.0 viewer metadata font too dark
When I use the viewer to show the book's metadata, with any viewer color setting, I get an info screen with unreadable details (dark background and extreem dark font). I can select the text to show that the info is there.
Is there some setting to change the meta data text font?

I tried to repro, out of curiosity, but couldn't reproduce in any viewer color setting (sepia, system, whatever). Never noticed calibre gets that info from <dc:description>. I always thought that was the #comments column.

Comments/comments (no hash) is calibrese for dc.description, like Tags/tags is calibrese for dc:subjects.

I can reproduce, with Sepia Light and never.

> Comments/comments (no hash) is calibrese for dc.description

What I meant is that, if you have the Comments column populated (different content), calibre will get the dc:description instead:

Curious : Where did you do this to the Comments column?

The Comments column I placed on the left side is a clone, see:

Click image for larger version Name: 2026-02-28 19_28_06-Edit custom column.png Views: 14 Size: 19.5 KB ID: 221494

I create Comments column clones according to the display format I need, such as trimmed, non-trimmed... currently I have comment2, and comments3.

This way I can get my Author Bio column, by checking its 'Show with comments in Book Details, display on the right.

--

Here is another example of what I said about the dc description:

Click image for larger version Name: MWSnap 2026-02-28, 19_25_06.png Views: 15 Size: 424.4 KB ID: 221495

The comments, in that case, were fetched from online metadata providers.

As i said, what I hadn't noticed is that calibre is using dc:description in viewer metadada.

AFAIK - the viewer only displays Dublin core elements, if you want custom columns to be eyeball-able in an EPUB you can use a jacket - Modify EPUB has an option to put them at the back.

Yes. And regarding the OP observation, I wonder if the dark issue occurs with other books.

In that case, twice. Sometimes I forget the option "Append comments to existing" checked.

If your comments specify their own colors then that can happen. Check the HTML for it. And if you want to see the contents of the comments column rather than what is inside the EPUB's OPF use the embed metadata too to updatethe EPUB before viewing it.

That was it, thank you. There are so many tools, I sometimes forget which one does each thing.

They do: Of course I tried several to be sure before reporting this.
I also checked earlier on the HTML source via "Edit matadata individually" for hidden colorizing before updating with the "Embed metadata" feature as suggested by Kovid: they were clean.

P.S.: just to test I did put colorization in the HTML and embedded it. The result is about the same: sometimes just a trifle lighter, but not by much.
