## Discussion

Discussion Use brightness(_:) to brighten the intensity of the colors in a view. The example below shows a series of red squares, with their brightness increasing from 0 (fully red) to 100% (white) in 20% increments. struct Brightness: View {     var body: some View {         HStack {             ForEach(0..<6) {                 Color.red.frame(width: 60, height: 60, alignment: .center)                     .brightness(Double($0) * 0.2)                     .overlay(Text("\(Double($0) * 0.2 * 100, specifier: "%.0f")%"),                              alignment: .bottom)                     .border(Color.gray)             }         }     } }
