On an email list why is the Yahoo smiley next to a name brighter than other smiley faces?



I was just curious to find out because a lot of my friends have Yahoo IDs. Whenever I am reading a forwarded message sent to a group of people, those who have Yahoo IDs have the smiley face next to their address, but sometimes one smiley face is brighter than the other. Does that mean that they are logged into their email at that moment?
