The Colorful Secret Women Don't Want Us To Know

This is just a short post about a brilliant viral marketing campaign that is happening right now which you might have already seen. Women around the world are just posting a color in their Facebook status updates and sharing it with their girlfriends only. The whole thing is designed to raise awareness about breast cancer and (presumably) to remind women to get examined. the colors are meant to be what color bra you are wearing at that particular moment. There are at least three reasons this is turning into a highly viral thing:

1. It is a secret. Keeping this limited to women only helps make it something women are more likely to pass along.
2. It needs explanation. Unlike many other things that you get right away, seeing just a color and nothing else in a status update is cryptic. It invites you to ask why ... and therefore gets you talking about it.
3. It isn't branded or monetized. The marketer in me immediately looks for the brand or organization behind this, but it seems that no one knows - and therefore this is already managing to spread to a level that perhaps would have been impossible if it was claimed by any one organization.
