The following example shows two versions of the same image side by side; at left is the original, and at right is a duplicate with the colorMultiply(_:) modifier applied with purple.


struct InnerCircleView: View {
    var body: some View {
        Circle()
            .fill(Color.green)
            .frame(width: 40, height: 40, alignment: .center)
    }
}


struct ColorMultiply: View {
    var body: some View {
        HStack {
            Color.red.frame(width: 100, height: 100, alignment: .center)
