`colorPalette`	Default series colors (when `series.color` not set)
`fontFamily`, `fontSize`	Text styling

Presets

'dark'
(default), 'light' — string presets
darkTheme, lightTheme
exported ThemeConfig objects
getTheme(name)
returns preset by name

Usage

TypeScript

// Preset theme: 'dark' | 'light' // Partial override (merges onto dark) theme: { backgroundColor: '#1e1e2e', colorPalette: ['#ff6b9d'] } // Palette-only (replaces theme.colorPalette) theme: 'dark', palette: ['#FF6384', '#36A2EB']

Color precedence: lineStyle.color / areaStyle.color > series.color > theme.colorPalette.
