What color can the goal posts be painted?

The goal posts in high school football are required to be a color that can be easily identified by both players and officials during the game. The NFHS (National Federation of State High School Associations) rules specify that goal posts should be painted white, as this color stands out well against various field types and conditions, providing clear visibility. While silver can be used in some instances, white is the traditional and standard color for goal posts. Yellow, while it can be a vibrant color, is not typically associated with goal posts in NFHS regulations.

The presence of white in the correct answer aligns with these requirements, making it the right choice. The other options contain colors that are not standard for goal posts as per NFHS guidelines, thereby leading to their exclusion.
