Does anybody know how to wire this - colored fog light switch?

[Spyder Hawk]

I am trying to replace the switch on my fog lights and the supplied wire diagram just doesn't make any sense to me. The simple off / on push button switch works but I wanted to be able to distinguish off from on a little simpler. I got this two color latching switch from Amazon but I can't get it to work. The diagram doesn't help because it seems backwards to me. Red is the negative and black is the positive on this switch for some reason. I got the switch to work but only one color which defeats the purpose of doing this. Can anyone offer some guidance?
