flashplayer brightness and contrast settings

Hi,

I just want to know that is there a way to change the brightness and contrast for a flash application? we have found that flashplayer  8 and 9 dims the background colour when idle but with latest versions of flash player from 10,11 onwards there is a lot of brightness in ScreenSaver idle conditions.

Seems Flashplayer 8, 9 uses black background, so when we dim this for idel scenario's we can see the screensaver patch color is darker in color black.

And with flash player 10, 11 onwards  we can see the white color.

Can you please help us out in this?

Regards,
