This is an indication you should look into calibrating your display. Right now, you're probably missing more than ad-outlines. It doesn't take very long.

But most people don't know their monitors can be calibrated, let alone how to do it.

So Google could chose colours that are less likely to be lost on poorly calibrated monitors.

What color do you suggest without making the text of the ad illegible? Perhaps a bright red border around the ads?
