The first single released from Red Green Blue is Child At Heart. The song is sung by Taylor Hanson and co-produced by Taylor, Jim Scott and David Garza. Says Taylor: "The song "Child At Heart" is about remaining open and hopeful despite the obstacles of life’s journey. Like a child whose heart is yet to be discouraged by the tribulations of the world."

The second single released from Red Green Blue is Write You A Song. The song is sung by Isaac Hanson and is a song written especially for his daughter Odette. The music video shows the pair at various places throughout their hometown of Tulsa, OK, including Buck Atoms on Route 66, Dust Bowl Lanes, and Antoinette Baking Company.

The third single released from Red Green Blue is Don't Let Me Down. The song is sung by Zac Hanson featuring Zach Myers of Shinedown. According to Zac, the song is "all about seizing your moment. It’s about living up to your potential." The hilarous music video takes place in a gym with plenty of muscles, short shorts, and Frankie Muniz in a starring role.
