Frequently Asked Questions

How do I use Color.indigo in SwiftUI?

In SwiftUI, apply the color directly using view modifiers like .foregroundStyle(.indigo), .tint(.indigo), or .background(.indigo). You can also instantiate it via Color.indigo.

What is the HEX code for SwiftUI Indigo in light and dark mode?

In light appearance, SwiftUI Indigo resolves to #6155F5. In dark appearance, it automatically adapts to #6D7CFF.

What is the UIKit and AppKit equivalent of SwiftUI Color.indigo?

The UIKit equivalent is UIColor.systemIndigo (accessible in SwiftUI via Color(uiColor: .systemIndigo)). The AppKit equivalent is NSColor.systemIndigo (accessible via Color(nsColor: .systemIndigo)).

Does SwiftUI Color.indigo adapt automatically to dark mode?

Yes, Color.indigo is a dynamic Apple system token that automatically updates between light (#6155F5) and dark (#6D7CFF) appearances when the system appearance changes.

What is the Display P3 and sRGB value of Color.indigo?

Color.indigo uses resolved sRGB values (#6155F5 in light, #6D7CFF in dark) and supports wide color gamut Display P3 coordinates for high-fidelity rendering on Apple Retina displays.
