How to change comment colors?

In my Linux/Debian/KDE system, the spreadsheet cell comments display as white on pale yellow and are not readable. How do I change that?

The setting is under Tools / Options / LibreOffice / Appearance / Custom Colors / Spreadsheet / Notes Background


Actually you just found an inconsistency… The option should be named Comment Background instead of Notes Background. Would you like to report this in bugzilla?

on the toolribbon for fromatting – You will see a “colour” drop-down or and a paint-can “backgrouind colour” – try that.
