HarmonyOS Toggle组件enable为false，组件selectedColor颜色变暗

点击Toggle组件根据接口的返回去改变Toggle的状态，封装了如下SwitchButton组件，将Toggle设置enable为false将点击事件设置在其父组件上，根据点击父组件调用接口并修改Toggle的状态，但是目前碰到一个问题，将Toggle设置enable为false后，Toggle的selectColor的颜色值会变暗和实际设置的值不一样，如何解决这个问题？

@Component
export struct SwitchButton {
  @State selectedColor: ResourceColor = $r('app.string.switch_button_selected_color')
  @State unselectedColor: ResourceColor = $r('app.string.switch_button_unselected_color')
  @State pointRadius: number | Resource = $r('app.string.switch_button_point_radius')
  @State pointColor: ResourceColor = $r('app.string.switch_button_point_color')
  @State trackBorderRadius: number | Resource = $r('app.string.switch_button_track_border_radius')
  @State sbWidth: Length = $r('app.string.switch_button_width')
  @State sbHeight: Length = $r('app.string.switch_button_height')
  @Prop isOn: boolean = false
  action?: (isOn: boolean) => void

  build() {
    Stack() {
      Toggle({ type: ToggleType.Switch, isOn: this.isOn })//TODO:设置的颜色值会变暗
        .enabled(false)
        .selectedColor(this.selectedColor)
        .switchStyle({
          pointRadius: this.pointRadius,
          trackBorderRadius: this.trackBorderRadius,
          pointColor: this.pointColor,
          unselectedColor: this.unselectedColor,
        })
        .width(this.sbWidth)
        .height(this.sbHeight)
    }
    .backgroundColor(Color.Transparent)
    .onClick(() => {
      this.action?.(this.isOn)
    })
  }
}
