A small but important feature of MeBeam, is the ability to know who said what, in the MeBeam chat window, without the need to have a username.
This is accomplished by taking a snapshot of the person who typed in the chat window, so you can identify that person by their web cam image.
Unfortunately, not everyone has a web cam, and until now, these users all appeared as a light greenish blue box.
To differentiate chat messages from people without cam, I have now made it so, that these users has a unique color.
Now you should be able to determine who said what, unless of course your color blind.
