Pure Dark Theme

Slight, cleaner variation on original Dark+ theme

"workbench.colorCustomizations": {
	"[Default Dark+]": {
		"titleBar.activeBackground": "#202020",
		"titleBar.border": "#242424",
		"editor.background": "#141414",
		"sideBar.background": "#191919",
		"activityBar.background": "#242424",
		"tab.inactiveBackground": "#202020",
		"tab.hoverBackground": "#323232",
		"statusBar.background": "#191919"
	}
},

Code/Codium Differentiator

Red titlebar to distinguish VSCode windows (Codium preferred):

"workbench.colorCustomizations": {
	"[Default Dark+]": {
		"titleBar.activeBackground": "#aa5555",
		"titleBar.inactiveBackground": "#883333"
	}
}
