This has been killing me for three days. I've been changing up the original NSeries theme, darkening some elements - slight color changes, things like that. Everything comes out perfectly except for a generic button. The element I'm trying to change is the normal thumb button, as in, click Conversations, and it's the one used for New SMS and New IM as well as many many many other buttons throughout the OS. That's the button I want to change. I want it darkened - almost black - so I've been using the GIMP as well as WinSCP to edit and replace. Every other theme element changes upon cycling the themes but this one refuses to change. Can anyone tell me exactly what the image is called?
