During a field inspection, if the corner flags are not orange, what is the correct response by the referee?

The correct response is that it is permitted for the corner flags to not be orange. According to the Laws of the Game, corner flags must be at least 1.5 meters high and should be identifiable but do not necessarily have to be of a specific color, such as orange. Therefore, if the flags do not meet the specific color requirement but still meet the other structural requirements, the match can proceed without interruption.

This interpretation aligns with the flexibility allowed in match officials' decisions regarding equipment that does not explicitly require adherence to color specifications. The other responses imply a strict requirement or necessitate a change or delay that isn’t supported by the regulations, thus they would not be appropriate actions in this situation.
