A person with color blindness may find it challenging to obtain employment, particularly in positions that need the ability to distinguish or see colors accurately. As the world's largest producer of palm oil, Indonesia employs a vast number of people in this industry. To discern between ripe and unripe oil palm fruit, harvesting jobs for oil palms is one of the occupations that require excellent color recognition skills. In the lack of a practical test method to determine the eligibility of a color blind oil palm fruit harvester, a simple yet effective test that can be modified for each enterprise is required.
