Which colors are allowed for wind direction streamers on the goal posts?

The regulation regarding wind direction streamers on goal posts specifies particular colors to maintain uniformity and visibility during games. The correct choice includes colors that are appropriate and easily visible against the background of the field and the sky, ensuring that players, officials, and spectators can easily see the direction of the wind.

Red, orange, and yellow are recognized for their high visibility and contrast in a variety of weather and lighting conditions. This enhances safety and functionality during the game, as players can quickly assess wind conditions, which may influence gameplay strategies, especially in passing or kicking situations.

The other color combinations either do not conform to visibility standards or are less effective in providing clear guidance about wind direction, making them unsuitable for use in this context.
