iron gray

The speaker looked up to meet the gaze of an iron-gray man with a harsh, sallow face.

And, since he was her betrothed, one or two iron-gray hairs in the man's head had turned white, and lines deepened in his face.

Right behind him was a tall, spare feller, with black eyes and straight iron-gray hair.

He had high cheek bones and iron-gray hair which he wore rather long, and very black eyes.

His long iron-gray hair fluttered in the wind, and his face seemed like a wizard's, penetrating but unearthly.
