About 15 months ago, our non-profit Amber's Last Promise, began using the lime green lapel pin as a means to make people aware of the importance of Mental Health Awareness and Suicide Prevention. It has provided us the opportunity to provide information re my step daughter's years-long battle w/mental illness and her eventual suicide two years ago. Our charity's Board of Directors chose the lime green as its color of choice because it "stands out" so profoundly and draws comments from people who see it and, eventually, receive it from us.
