Any way to change the background color?

Hey everyone, just got my PSP in the US a little while ago. I've seen advertisements with Red backgrounds and everything shows that the PSP is supposed to have a blue background, but mine is green. What gives? Is there any way to change it? WIll I have to wak e for the hackers to let me know how to modify various system settings? Or will Sony provide this option in a firmware update?

Just curious, I figured Sony would let us change the color at least but I see no option for that, and it says nothing in the manual.

Well I just found out, it changes depending on the month. Next month I believe it is going to be purple, wierd. You think there will be a way to customize our PSP's to the color we want?
