Overview

ColorScheme creates an empty registry, checks that the key and color arrays stay the same length, and adds, reads, or renames entries by unique keys. Duplicate or missing keys raise runtime errors. It draws nothing and has no signals, entries, exits, or position rules. Callers supply the keys and colors.
