irssi highlights in yellow on a white background

On the IRC client irssi, when your nick is included in a message, that message's nick is highlighted in yellow to alert you. Unfortunately, yellow is difficult to read on a white background.

The highlight color is defined in the default theme file. On Ubuntu this is located at:

/usr/share/irssi/themes/default.theme

Edit the line:

menick = "%Y$*%n";

This is currently highlighting your nick to yellow. Change it to

menick = "%G$*%n";

to make it green, which contrasts better against a white background.
