I love our traditional white and gold. That being said I think it would appeal to the kids to bring back some black into our uniforms. Black helmets with all black uniforms (Just for a game or two). That or all navy blue with white or gold helmet. I know this sounds extreme but the kids would respond well. Black is a popular color in uniforms and we used to wear black jerseys. No need to get extreme with the patterns (i.e. honeycomb / hexagon look) just switch up the color scheme every once in a blue moon and keep the patterns /designs simple. Again this is jmo. Take it with a grain.
