Preset Themes

The four presets

Pick a visual identity. Ship in one line.

Each preset varies colors, corner radius, and shadow weight. Typography, spacing, and animation stay consistent across all presets — only the identity changes.

Live previews

Light and dark, out of the box

Every preset ships both a light and a dark theme. The dfThemePreset() modifier selects the correct variant automatically based on the system color scheme.

Default — System semantic colors. Fully adaptive, no preset required.

.slate — Professional, navy-slate brand. Default radius and shadows.

.aurora — Electric violet. Rounded corners, soft shadows.

.copper — Warm amber on cream. Sharp corners, defined shadows.

.sage — Deep sage green. Very rounded corners, airy shadows.

API

Three patterns, one type

The common case is one modifier at the app root. Power users can go deeper.

Common case — automatic light/dark

import DesignFoundation

@main
struct MyApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
                .dfThemePreset(.aurora) // reads \.colorScheme, switches automatically
        }
    }
}

Force a specific appearance

// Force dark in Xcode Previews
ContentView()
    .dfTheme(.auroraDark)
    .environment(\.colorScheme, .dark)

// Force light for a sub-tree
HeroView()
    .dfTheme(.slateLight)

Custom preset

// Mix preset themes — light from one, dark from another
let myPreset = DFThemePreset(light: .slateLight, dark: .auroraDark)
ContentView().dfThemePreset(myPreset)

// Extend a preset with one token override
var custom = DFTheme.sageLight
custom.colors.primary = .purple
MyView().dfTheme(custom)

Under the hood

How presets work

The implementation is a thin wrapper over the existing dfTheme() environment system.

Color reference

Full palette tables

Every color token for each preset. respectsColorScheme is false on all preset tokens — switching is handled by the modifier.
