Hi all, I want to make default light FlatLat theme a little darker. I tried to modify netbeans-14/netbeans/platform/modules/org-netbeans-swing-laf-flatlaf.jar#org/netbeans/swing/FlatLaf.properties file , but it seems that all modifications in this file are ignored. For example, I set: nb.multitabs.background=#ff0000 nb.multitabs.foreground=#ff0000 nb.multitabs.activeBackground=#ff0000 nb.multitabs.selectedBackground=#ff0000 nb.multitabs.selectedForeground=#ff0000 nb.multitabs.hoverBackground=#ff0000 nb.multitabs.underlineColor=#ff0000 nb.multitabs.inactiveUnderlineColor=#ff0000 And there are no changes in the appearance. Could anyone say how to do it? -- Best regards, Alex Orlov
