Which eye color has the gene combination to deposit the most melanin in the iris?

Brown eye color is associated with the highest levels of melanin in the iris, due to a dominant gene combination. Individuals with two copies of the brown eye allele (homozygous) or one brown allele and one blue allele (heterozygous) typically have more melanin than those with blue or green eyes. This increased melanin concentration results in the darker pigmentation characteristic of brown eyes.
