Redheads

I'm not ashamed to admit that I kinda have a thing for rangas, gingers, redheads, whatever you prefer. I don't know what it is. But lately I have been noticing a lot of redheads in adds. For instance, that little annoying one talking about the car. Then when I started to think about it and pay attention, you can't go through an add break without seeing a redhead. Why?
Firstly, redheads, representing under 2% of the population, stand out. They are uncommon, just rare enough to be interesting and catch our attention but just normal enough to still be liked. We're more likely to pay attention to someone who stands out rather than someone that just looks like everyone else.
Secondly, they are recognisable. Well, I believe a redhead is more likely to be recognised again rather than a brunette or blonde because they're different and being different is an important brand attribute.
Finally, when you only have 30 seconds to portray your message in an add you need to make every second count. The consumer needs to be able to easily portray the story you're trying to tell without confusion and redheads easily do this. For example, you can show a younger red head and then an older one and the audience can easily tell that it's suppose to be the same person over a period of time.
