Package-level declarations

The color system: the generated primitive palette, the semantic JengaColors roles (brand, surface, textPrimary, success…) that flip for dark mode, and withBrand, a lower-level helper that rebrands a single palette (prefer jengaBrand(seed = …) to brand a whole light+dark theme).

Types

JengaColors

@Immutable

class JengaColors(val brand: Color, val onBrand: Color, val brandSubtle: Color, val onBrandSubtle: Color, val ink: Color, val onInk: Color, val background: Color, val surface: Color, val surfaceVariant: Color, val surfaceSunk: Color, val textPrimary: Color, val textSecondary: Color, val textMuted: Color, val textFaint: Color, val border: Color, val borderStrong: Color, val contentDisabled: Color, val surfaceDisabled: Color, val borderDisabled: Color, val inverseSurface: Color, val inverseOnSurface: Color, val success: Color, val successContainer: Color, val onSuccessContainer: Color, val warning: Color, val warningContainer: Color, val onWarningContainer: Color, val error: Color, val errorContainer: Color, val onErrorContainer: Color, val info: Color, val infoContainer: Color, val onInfoContainer: Color, val overlaySurface: Color, val onOverlay: Color, val onOverlayMuted: Color, val focusRing: Color, val scrim: Color, val isLight: Boolean)

Semantic color layer: colors named by role, not by hue.

JengaScheme

@Immutable

class JengaScheme(val light: JengaColors, val dark: JengaColors)

A light + dark JengaColors pair: a complete custom color theme as one object. Pass it to JengaTheme(scheme = ...) and the right scheme is chosen for the current darkTheme, so the caller never wires the selection themselves.

Functions

jengaDarkColors

fun jengaDarkColors(): JengaColors

The default dark color scheme.

jengaLightColors

fun jengaLightColors(): JengaColors

The default light color scheme.

withBrand

fun JengaColors.withBrand(brand: Color, onBrand: Color = this.onBrand, brandSubtle: Color = this.brandSubtle, onBrandSubtle: Color = this.onBrandSubtle): JengaColors

Multi-brand convenience: returns a copy of this scheme rebranded to brand. The semantic structure (surfaces, text, lines, status) is untouched; only the brand accent and its subtle/on pairs change.
