“Patterns” — a monochrome, texture-driven theme in the spirit of engraved or newspaper charts: every filled series shares one gray fill overlaid with a distinct white pattern (hatch / dot / star / triangle / grid), so series are told apart purely by texture rather than hue.

“Petroleum” — a restrained, near-monochrome dark theme: gas-flare gold text on a near-black crude ground, with a tight gold palette and a single industrial- green accent.

“Savanna” — a warm, editorial light theme: a cream / sepia ground with a muted, low-key palette of natural accents (amber gold, terracotta, olive, plum, ochre, walnut).

“Spirited Dark” — the Spirited palette on a dark ground. Reuses the Spirited series colors (lifting any too-dark entries so they read on the dark ground) and applies a neutral dark set of interface colors.
