So I was writing some CSS and assigning an rgb color and the R value was '192' so I typed out: rgb(192.168. before I caught myself. So then I was like, well what happens if I put an IP address in there? and... rgb(192.168.0.1) actually works?
FF and chrome both interpret it as rgb(192,0,0) which is a red color, but like the fact it doesn't error is pretty weird, rgb(192) errors.
