I don't see why you need the script to color your nickname when you can do it via nick colors. Why not add Deep3D under "Nick or Address(nick!user@host):" You can just put your nickname as Deep3D the way it is in the box, check it, without !user@host, and then select a color of your choice to achieve the same result of what you've shown at your first post.
As for your saying about highlight, and if the nickname doesn't flash anymore like you claim, you can just use Nick Color feature along with the highlight one matching message to get it flashing.
