The eye colour is mainly effected by the two components melanin and structural blue of the iris stroma which generally are present in various mixtures respectively combinations. Are these components lacking the dark pigment epithelium can produce a so-called "basic brown". The exact distinction between "brown" and "basic brown" is without doubt of considerable value for anthropological as well as for genetical examinations of eye colours.
