31,916 named colours in nine families. The boundaries are not decoration: each family is anchored on a colour nobody argues about — pure red, pure yellow, pure blue — and the line between two neighbours sits at the midpoint between their measured positions in OKLCh. Those positions are nothing like a colour wheel drawing: red sits at 29°, and green and cyan are 52° apart while cyan and blue are 69°. The boundary table.
