red hair
Let an agent explain red hair, relay genetics, distribution and cultural history from genetic and anthropological sources with attribution, describe the natural shades the registry aliases name, and distinguish natural red hair from blond, brown and dyed colours such as purple and violet, avoiding stereotypes and prejudice.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain red hair, relay genetics, distribution and cultural history from genetic and anthropological sources with attribution, describe the natural shades the registry aliases name, and distinguish natural red hair from blond, brown and dyed colours such as purple and violet, avoiding stereotypes and prejudice.
A human hair colour ranging from strawberry blond and light red through copper and auburn to dark red and titian, caused by high levels of the pigment pheomelanin associated mainly with variants of the MC1R gene, most common in northern and western Europe, especially Scotland and Ireland; the registry aliases also include violet and purple hair, which are artificial dyed colours rather than natural red shades.
What it is for: Not applicable; a physical trait.
It can be explain the trait; relay genetics and distribution; describe shades; distinguish related colours.
Distinguishing features
Pheomelanin rich
MC1R variants
Rare globally
Associated traits such as fair skin
What it looks like
Hair in copper, auburn, ginger or deep red tones.
Physical character
world population with red hair: about 1-2 percent - estimates
Scotland: about 6 percent - estimates
main gene: MC1R note - recessive variants
How it is recognised
Hair colour from high pheomelanin
Light red, dark red, auburn, titian; violet and purple as dyed colours
Blond hair has low eumelanin; brown has more eumelanin; purple and violet are dyes
