I can't make my battery icon on the home screen change, only in apps

[purplegem]

I'm trying to use Winterboard to change my battery header icon to purple - it seems to work when you launch an app like safari but its still white on the home screen. I've tried modding the white images but it still doesnt change. What's going wrong?

What did u name the icon? Where did u place it?

[purplegem]

Took a while but worked out where I was going wrong, I started with a battery header theme that was working and changed the images so I now have a nice purple battery

So you ended up changing it then? How?
Thanks
