I ran the demo from this jar: https://download.formdev.com/flatlaf/flatlaf-demo-latest.jar Adding "@foreground = #ff0000" did take effect - I got red font in various places.
Just had an epiphany: I have been adding "--fontsize 16" to netbeans.conf for years (old man, old eyes). I removed that and the "defaultFont=36" took effect. "--fontsize 16" must be overriding or inhibiting some of the FlatLaf settings. (A warning/error in this situation would be helpful.) Final contents of my ~/.netbeans/26/config/LookAndFeel/FlatLaf.properties file is: defaultFont = 16 Dialog, "Noto Sans", Roboto, Ubuntu, Arial, Monospace and is working just like I want it to. Also saves me a step updating netbeans.conf at upgrade time. Thanks all for the help! Suggestion: incorporate the FlatLaf demo/theme editor into NetBeans - making the changes on the fly and persisting them to ~/.netbeans/26/config/LookAndFeel/FlatLaf.properties (or wherever).
