Login popup help please

[Genestoy]

Just upgraded my test install to 4.7.2.1 and need some help with customizing the login popup. I have gone to the template loginpopupform to add some html color etc and nothing seems to be working, can anyone tell me why anything I do in that template does not change the popup, or am I in the wrong template? I am talking about the popup in the pic below.

Thanks
