No FG Forum background with Safari

[Kedjane]

When I use IE there's a background. Dark grey with a bright grey beehive pattern, it's really nice. If I right click on it and choose save it's named bee-something. In Safari it's just grey and there's no option to save the background at all. I wonder if there's similar differences on other sites aswell or if the forum designers simply put a wrong tag somewhere.
Text colors may very well be a web browser setting though, some sort of color restriction.
