Mac-PC: why different!?

[DuffyStark]

I have a problem: I have a site on line (www.sogega.com); I modified the swf, but I didn't touch the bk color!! It is grey, 333333, I only modified a simbol and set the swf to 100% and "no border"... but now if I use a PC to connect to the site I see a violet-blue background color!!! Using Mac, instead, it is perfecly grey!!
Why!?
Maybe because I've made the swf on a Mac?
I'm confused...
I hope someone will help me :(
