You know, I've clicked on those warning messages for the better part of 10 years now, and never once noticed that some of them were red and some were orange. It's exactly the same dialog, with exactly the same fields. The only difference is an icon that you'd never realize was different unless you had two dialogs open side by side. If a guy who writes software for a living can't tell them apart, I don't think the average user stands a chance. If they actually want to fix this, they need completely different looks for the two popups. Or better still, simply skip the warning altogether for signed apps. If you downloaded it off the internet with the intention of running it, you're going to want to run it. Popping a dialog in your face isn't going to change that fact.
