Color.PaletteError exception (Color v0.11.0)

Raised when a palette cannot be generated — typically because of invalid options (bad stop list, out-of-range anchor, unreachable contrast target, etc.).

Has fields:

• :reason — a short atom describing the failure (e.g. :empty_stops, :duplicate_stops, :invalid_anchor, :invalid_seed, :unknown_option).

• :detail — a human-readable string with more context.
