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)
}
}
}
