iframe background color issue

iframe background color

[Blade Runner]

I have an iframe embedded in plain old html and the html page's background is black. Now that I've placed an iframe in the page, the background changes to white until I click a link that places an html table in the iframe. I want to make the background area that encompasses the iframe to black, rather than white. How can I accomplish this?

Have the iframe open on a default html page with a black background color, a blank page that is, except with body {background-color:black;}.

<iframe src="black.htm"> etc
