The iconic Welcome to Las Vegas sign became blue Wednesday for National Foster Care Month.

May is dedicated is raising awareness of the 400,000 children and teenagers in foster care around the country.

In Clark County, more than 3,000 children are in foster care system on any given day. Many of those children cannot return home because their families are in crisis.

"We really need to get more of our community together and try to help the foster kids that are out there. My foster parents have been the most amazing blessing to me, and I just love to see all this advertisement for it," foster child Anny Anderson said. 

The county's Department of Family Services would like to people to be aware of the ways they can help these kids in need.

The iconic Welcome to Fabulous Las Vegas sign turned green in honor of St. Patrick's Day.

The sign that has welcomed visitors to the Las Vegas Strip for years was turned green Wednesday night by former city of Las Vegas Mayor Oscar Goodman and Kathryn Thomas, a judge from the Irish TV show "The Voice Ireland."

The sign is one of several iconic structures around the world that is going green for St. Patrick's Day, including the Pyramids of Giza, the Leaning Tower of Piza and the Christ the Redeemer Statue in Rio de Janiero.

The color change is part of a partnership between the Las Vegas Convention and Visitors Authority and Tourism Ireland.

This is not the first time the sign has switched its color. It was turned pink in October in honor of Breast Cancer Awareness month. That same month it turned purple to show solidarity against bullies.
