Detecting when macOS 10.14 accent color has changed

Question

In macOS 10.14 you can detect when the system theme has changed by listening to the following notification:

[NSDistributedNotificationCenter.defaultCenter addObserver: self
                                                  selector: @selector(OSThemeChanged:)
                                                      name: @"AppleInterfaceThemeChangedNotification"
                                                    object: nil];

But this does not get fired when the Accent color changes (NSColor.controlAccentColor). I have an image I want to modify based on the accent color, so I would like to know when it changes.

Has anyone been able to figure this out?

AppleColorPreferencesChangedNotification key should work I believe:

    [[NSDistributedNotificationCenter defaultCenter] addObserver:self
                                                        selector:@selector(accentColorChanged:)
                                                            name:@"AppleColorPreferencesChangedNotification"
                                                          object:nil];

Notification isn't sent until the preference is changed and the system preferences general window is closed.

Couldn't find the documentation to link to for it though.
