- Red hair is found on people lacking pro-opiomelanocortin.

“With the old kindness, the old distinguished grace,
She lies, her lovely piteous head amid dull red hair
Propped upon pillows, rouge on the pallor of her face.

And when she meets our gaze her eyes are laughter-lit,
Her speech a wicked tale that we may vie with her....”

In an old cellar hole in a byroad
The origin of all the family there.
Thence they were sprung, so numerous a tribe
That now not all the houses left in town
Made shift to shelter them without the help
Of here and there a tent in grove and orchard.”
—Robert Frost (1874–1963)
