# contrast(_:) Sets the contrast and separation between similar colors in this view. ``` nonisolated func contrast(_ amount: Double) -> some View ``` ## Parameters `amount` The intensity of color contrast to apply. negative values invert colors in addition to applying contrast. ## Return Value A view that applies color contrast to this view. ## Discussion Apply contrast to a view to increase or decrease the separation between similar colors in the view. In the example below, the `contrast(_:)` modifier is applied to a set of red squares each containing a contrasting green inner circle. At each step in the loop, the `contrast(_:)` modifier changes the contrast of the circle/square view in 20% increments. This ranges from -20% contrast (yielding inverted colors — turning the red square to pale-green and the green circle to mauve), to neutral-gray at 0%, to 100% contrast (bright-red square / bright-green circle). Applying negative contrast values, as shown in the -20% square, will apply contrast in addition to inverting colors. ``` struct CircleView: View { var body: some View { Circle() .fill(Color.green) .frame(width: 25, height: 25, alignment: .center) } } struct Contrast: View { var body: some View { HStack { ForEach(-1..<6) { Color.red.frame(width: 50, height: 50, alignment: .center) .overlay(CircleView(), alignment: .center) .contrast(Double($0) * 0.2) .overlay(Text("\(Double($0) * 0.2 * 100, specifier: "%.0f")%") .font(.callout), alignment: .bottom) .border(Color.gray) } } } } ```  --- Copyright © 2026 Apple Inc.
