Although the physical ideal of these racial theorists was typically the tall, fair-haired and light-eyed Nordic individual, such theorists accepted the fact that a considerable variety of hair and eye colour existed within the racial categories they recognised. For example, Adolf Hitler and many Nazi officials had dark hair and were still considered members of the Aryan race under Nazi racial doctrine, because the determination of an individual's racial type depended on a preponderance of many characteristics in an individual rather than on just one defining feature.
