Joe Jackson eye color
Joe Jackson, the father of Michael Jackson and patriarch of the Jackson family, had naturally green eyes (source, source). This distinctive feature was not due to contact lenses but was his natural eye color, which was quite unusual given his ancestry (source). His green eyes were likely a result of the mixed genetic heritage in the Jackson family lineage (source).
Genetic Background
The presence of green eyes in Joe Jackson can be traced to his mixed racial ancestry. Both of Joe's parents were of mixed race - his mother Crystal and father Samuel had diverse genetic backgrounds that contributed to this unique trait (source). This genetic diversity in the Jackson family would later become evident in subsequent generations, including some of his grandchildren who also inherited light-colored eyes (source).
Legacy
The genetic trait of light-colored eyes has appeared in multiple members of the Jackson family. Most notably, Paris Jackson, Michael Jackson's daughter, also has green eyes - a trait that can be directly linked to her grandfather Joe Jackson (source). This genetic inheritance has been one of the identifying features that demonstrates the family's diverse genetic makeup and has been passed down through generations (source).
