Construction signs use orange backgrounds because this color is reserved for temporary work zones in standard traffic sign systems. The bright orange quickly signals drivers that conditions may change ahead, with workers, equipment, or lane changes, so they should slow down and proceed with caution. Other colors have different meanings—blue for services, green for guidance, red for prohibitions or stops—so orange is the specific choice for construction and maintenance warnings.
