The strategic use of a particular color of illumination on October 31st indicates a specific intention. This color, when displayed on a porch or at a residence, signals that the homeowner is participating in a specific cause. For example, a family might choose to illuminate their home with blue to show support.
This practice raises awareness about a cause that affects many families. By displaying the designated color, individuals can promote understanding and acceptance within their communities. The visual signal serves as a simple, yet effective, way to demonstrate solidarity. The origins of this specific color choice in October are tied to efforts by advocacy groups.
