How to change the border colour of the Row Numbers and Column Names in Calc?

Hello all, hope you’re well. I recently installed LibreOffice and was customizing it to suit my needs. This is the first time I’m using LibreOffice.

I installed the Dark Gray theme from the Extension portal and then I edited the theme to make it darker. I customized the colours from Customization section in Tools > Options > LibreOffice > Appearance. However, I’m not aware which of the Customization Items corresponds to the colour of these borders that I marked in the screenshot.

Which option under the Items menu would change the colour of these borders?

Do you mean the background color of the column header (A, B, C…) and the row header (1, 2, 3…)?

Or do you mean the grid lines (“border”) color of these row and column headers?

As far as I can tell, it is Window color but with added grey, that is, it cannot be coloured separately.

No, I know what the window colour changes. I meant the Borders or the letters/names themselves.

Yes, the grid lines or borders of those column and row headers. And also the headers’ font colours too, if possible.
I know the background can be changed using the Window Colour.

No such settings afaik.
Even under advanced settings >> expert configuration I can’t find a “candidate” name for such exotic settings.

There has to be something, otherwise running light mode would make it white-on-white and it’ll become invisible. I know some of the items are connected with others, like Window Colour setting the colour for panels that occupy the most space in the tool-set area.

I thought maybe one of the Automatics, but I couldn’t find anything set to Automatic that changed the colour of those grids/borders of the column and row headers.

Did you try?
I would suppose there is a kind of automatic styling of the component window.
At least it works this way for me under Win 10. Last checked with LibO V25.2.0.3.

I found it! It’s the Shadow Colour. I skipped some of the options because of what the names were, but now I decided to check each and every one of them and found it. Don’t know why it’s called that, but I guess it’s the same as some other item affecting other seemingly unrelated items.
