Why is the Georgia World Congress Center bathed in purple light?

The spectacle is being put on by Understood.org, a resource offering a community for parents with children who have the disabilities highlighted by the month.

The group hopes shedding more light will help encourage parents to get their kids tested earlier. When disorders like dyslexia and ADHD are identified and treated early, it can prevent issues like bullying and  school suspension, according to Understood.org.

While the purple light will only be up for three days, Learning Disabilities, Dyslexia and ADHD Awareness Month lasts through the end of October.
