Color dot meaning in Firewall pane.

This dot takes on different colors on my various Macs.  I can't find anything in the OS X documentation that describes its meaning.  Anyone know?  Thanks.

The dot is green when you turn on the firewall. But if, under Firewall Options, you turn on "Block All Incoming Connections" then it turns yellow to warn you that this may disable some functions in the system and some apps.
