Know Number of colors

[orion_rus]

Hello world again.
I find some problems with opacity if user have less than 24 bit color. Opacity items seems very bad on it.
May be somebody solve this problem or know function what returns number of colors?
Thanks in advance

Search under the terms "screen.pixelDepth" (netscape) and "screen.colorDepth" (IE).

Perhaps you could just do an either/or:

var depth = screen.colorDepth¦¦screen.pixelDepth
if(depth) alert(depth)
