Which of the following colors is best used for surveyor markings?

1. Fluorescent green

2. Fluorescent pink

3. Fluorescent orange

4. Fluorescent blue

The correct answer is: Fluorescent pink

Fluorescent pink is the best color for surveyor markings because it is widely recognized and utilized for indicating temporary survey markings in a variety of contexts, including construction and land surveying. This color stands out clearly in outdoor environments, making it easily visible to workers and others who may be operating in or around the marked areas. Fluorescent pink is often associated with specific types of markings, such as those indicating proposed excavation or survey-related disturbances, which is vital for maintaining safety and awareness on job sites. Its high visibility helps prevent accidents by ensuring that important information is noticeable at a distance. In contrast, the other colors have different specific applications. Fluorescent green may be used for permanent survey markings, fluorescent orange generally signifies construction and excavation, and fluorescent blue is typically utilized for water utility markings. Each color serves its respective purpose, but for surveyor markings specifically, fluorescent pink is the standard.
