Paul , The icon used is > /usr/share/notify-osd/icons/gnome/scalable/status/notification-gsm-3g-full.svg
The grey *is* the signal strength, those icons were designed for notify-osd to display on a black background.
From your screenshot , the icon theme you are using isnt humanity-icon-theme. [Since humanity's panel icons are monochrome , notice the color battery and the apport crash icons]
It looks like you are using the gnome-icon-theme , or a theme which doesnt have those icons and hence fallsback to the gnome icon theme
Kindly switch icon them to humanity. [System > Appearance > Theme tab , Customize > Icons tab]
The other issue is the nm-applet currently does not support signal strengths for the gsm , it only uses one icon , and hence the problem.
Do report back if switching the icon theme to humanity fixes the problem.? [if you are on Karmic or Lucid]
[Just to remind again : The signal strengths has yet to be implemented in nm applet]
