And here I was thinking she'd had a garbled recollection of the description of Cu Chulainn:

"His hair was black at the roots, blood red in the middle, and gold at the ends, and said to either be very smooth or sticking up in the front. Seven pupils of seven colors were in each of his eyes, with the light of seven diamonds in each pupil. Each hand had seven fingers and each foot seven toes, with the grasp of a hawk in each."

(Strangely, most artists depict him as quite human.)
