“Pastel Dark” — the dark counterpart to Pastel: a deep, desaturated ground with soft, chalky pastels that glow gently against it.

“Pastel” — a soft, low-saturation light theme on a warm off-white ground, with a muted pastel series palette. Calm and editorial. Pairs with PastelDark.

“Patterns Dark” – the dark counterpart to Patterns: every filled series shares the same gray ramp overlaid with a distinct black pattern (hatch / dot / star / triangle / grid) – the opposite pattern color to the light Patterns, so the texture reads as dark cuts into the gray on the dark ground. Line series are gray, told apart by stroke width and dash.

“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.
