High Visibility Colors

While watching TRON Legacy (which I would definitely recommend going to see), I realized that they all looked like they were ready to go for a nighttime run/ride. This got me thinking about the "best" color choice for such an occasion, so I decided to do some research. "Neon" was a popular choice, with yellow, green, and orange making the list. Most people on this forum noted that yellow and green stood out the best in headlights (I'm confused by the "lime yellow" description... limes are green), while traffic-cone orange stood out best when driver's are looking into the sun. Contrast was also important, and many people have seemed to embrace the "funfetti" neon color scheme (aka combining all 3 with black/white/gray contrast). I also came across an interesting site related to the effects of color blindness on daytime visibility (the main conclusion... blue and yellow are best).
