Suetonius described Caligula as sickly-looking, skinny and pale: "he was tall, very pale, ill-shaped, his neck and legs very slender, his eyes and temples hollow, his brows broad and knit, his hair thin, and the crown of the head bald. The other parts of his body were much covered with hair ... He was crazy both in body and mind, being subject, when a boy, to the falling sickness. When he arrived at the age of manhood he endured fatigue tolerably well. Occasionally he was liable to faintness, during which he remained incapable of any effort". Based on scientific reconstructions of his official painted busts, Caligula had brown hair, brown eyes, and fair skin.
