--- Comment #5 from Regina Henschel <rb.henschel at t-online.de> ---
Black would be better readable.

There exist calculation rules in https://www.w3.org/TR/WCAG21. Perhaps it
should be considered to use that rules to determine the threshold for switching
between white and black text color?

I don't think so. The switch between white and black text color works in
principle in Version: 25.2.0.0.alpha0+ (X86_64) / LibreOffice Community
Build ID: aaf2967d74a9a7ba2d28433e1872422ce38b6244
CPU threads: 32; OS: Windows 11 X86_64 (10.0 build 22631); UI render: default;
VCL: win
Locale: de-DE (de_DE); UI: en-US
Calc: default
However, the threshold value for the switch could be set better for greenish
colors.
