blond hair
Let an agent explain blond hair and its shades, relay genetics, distribution and cultural history from genetic and anthropological sources with attribution, describe the shades the registry aliases name, and distinguish natural blond hair from dyed hair, from red hair and from light brown hair, avoiding stereotypes.
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 blond hair and its shades, relay genetics, distribution and cultural history from genetic and anthropological sources with attribution, describe the shades the registry aliases name, and distinguish natural blond hair from dyed hair, from red hair and from light brown hair, avoiding stereotypes.
A human hair colour ranging from light yellow to golden and pale brown, caused by low levels of eumelanin, most common in Northern and Eastern Europe and also found among some Melanesians of the Solomon Islands through a distinct gene variant, with shades named platinum blond, light blond, ash blond, beige blond, strawberry blond and amber, and often darkening with age or produced by dyeing.
What it is for: Not applicable; a physical trait.
It can be explain the trait; relay genetics and distribution; describe shades; distinguish related colours.
