While I agree that perception of color is due to light reflection.
However, eye color is the determination of genes which limit melanin. One might say that blue is the default color of eyes, and it is degrees of the representation of a specific gene that throttles the amount of melanin in eyes. No melanin=blue eyes, green eyes=more melanin, brown=full expression (missing this gene).
A person expressing brown eyes is not necessarily missing the recessive gene for blue eyes. They could be heterozygous for brown eyes, having received the dominant allele (brown) from one parent and the recessive allele (blue) from the other.
I happen to be one such specimen. My father was homozygous for the recessive trait (had green eyes) and my mother was brown-eyed and heterozygous (brother has hazel eyes, meaning she had to carry the recessive gene as well.)
