Which ad formats/colors work for you?

I know, I know...

I know it all depends on your site's design and colors, etc.

But why should it be so wrong to discuss some general, good working, ad colors and formats? (And I don't think the Google default is a good one.)

My site has a white background and is basically a blank slate.

I have room for all size ad's and different kinds of color schemes.

Doesn't necessarily have to blend in, doesn't necessarily have to stand out.

Just want to know what colors and sizes work good for you.

Forgetting about the position on the page and your site's unique design, what do you think REALLY makes people click on those ad's?

Relevancy.

Large retangle works best for me, imbedded in content, with the content wrapping around. Colors? Blended to *almost* perfection. Leave it a little different. You want to thwart ad blindness, but you don't want to trick them into clicking either.
