A fascinating insight into how people see/distinguish colour.

We think of a physical object’s being a certain “color” as a solid, immutable property (grass is green, lemons are yellow, et cetera).

The Himba tribe of remote northern Namibia, to whom water looks “white” like milk and the sky looks “black” like coal, and who struggle to distinguish between blue and green, yet can easily pick out micro-shades which Americans cannot see.
