Semantic Colors: Naming a Color's Job, Not Its Value
Semantic colors name a color's purpose (e.g., `color-background-interactive`) instead of its value (`#007BFF`). This simplifies theming, like light/dark mode, by mapping roles to specific primitive colors, ensuring a consistent UI across an application.
SwiftUI Theming with the Environment
Treat SwiftUI's Environment as a cascading style sheet for your app. You define design tokens like colors and fonts once at the top, and all child views automatically inherit them. This is key for building design systems or multi-brand apps.
Jetpack Compose Theming for Design Systems
Compose theming uses `CompositionLocal` to implicitly pass design tokens like colors and fonts down the UI tree. This is key for building a design system where you can swap themes (like light/dark) without rewriting components.
White-Label UI: Design Once, Rebrand Infinitely
White-label UI is like a WordPress theme for your product: a single design that other companies can rebrand. It lets agencies serve multiple clients without rebuilding the UI from scratch.
Theming: One Design System, Many Visual Styles
Theming lets one component library wear many visual styles, like skins on a character. You can support multiple brands or dark/light modes by swapping design tokens instead of rebuilding components.
Theming in Compose: Style from a Single Source
Theming in Compose is like a CSS stylesheet for your app. You define colors, typography, and shapes once in a central `Theme` composable, and it cascades down. Use it for light/dark modes and brand consistency.
