Ability to set Font Color to 'automatic' for dark desktop?

[fwiep]

Hello all,

Using PhpSpreadsheet v4.3.1 with PHP v8.4.7 under Fedora 42 and LibreOffice v25.2.3.2.

My desktop environment has dark mode enabled. LibreOffice Calc normally renders white text on a dark-gray background. However, when I generate and open a spreadsheet from PhpSpreadsheet, the text's font color seems to be statically set to 'black', #FF000000. When I subsequently set the cell's font color to 'Automatic' (see screenshot), the text becomes white and is readable.

Is there something I can do in the generating of the spreadsheet to make the font color 'Automatic'? I have tried to load an existing spreadsheet with correct (automatic) color, but ...->getFont()->getColor()->getARGB() still shows FF000000.

Thanks, kind regards,
FWieP

Not available till now. Please let me know if PR #4503 meets your needs. As you can see in my comments there, I'm not entirely sure how this is supposed to work. I'm hoping that you can let me know of any problems, or edge cases that I might have missed.

The mentioned PR works perfectly, see my comment over there.

Is there a new PhpSpreadsheet release planned for the near future?

Thanks! Kind regards,
