It's funny. OpenNMS has an issue in its GUI that affects those with
red/green color blindness. We haven't really had time to address it, but
we need to. I used to give training courses on OpenNMS, and the usual
class size was around 10 people - almost always male. In *every* class I
had at least one person with red/green color blindness.
