You may have noticed that your friends have posted colors on their Facebook status when you recently logged into the popular social networking site. Some have listed "white", or "black" or "red" or maybe even purple with polka dots. Don't worry the site hasn't been hacked and your friends haven't gone raving mad. It's a special event taking place on Facebook.
The colors posted on Facebook represent female's bra colors, as part of a group effort to raise awareness for breast cancer. Females on the popular networking site all received a special email informing them of the group event on Facebook. This has prompted the big search for answers with people questioning why is everyone posting colors on Facebook. The question's been posted on several Q&A sites like Yahoo Answers.
So female users of Facebook who want to participate in the effort, log in to your account and post colors on your Facebook statuses!
