Using this example pretty much from the wiki:

At runtime get this error:

msg ("<color color="red">You can't move while in combat</color>")

Error running script: SyntaxError: Unexpected token "red" <IDENTIFIER>; expected one of <EOF> Line: 1, Column: 16

SOLVED. I needed to code it like this:

 msg ("<color color='red'>You can't move while in combat</color>")

The wiki/doc really should point that out as any real use would require using single quote as a msg string is always double quote delimited.

Or you can "escape" the double quotes using a backslash \
