the code is as follows:

handleSwitchColor = (color) => {
    console.log(color);
    const {store} = this.context;
    store.dispatch({
      type: "CHANGE_COLOR",
      themeColor: "red"
    })
  };
  render () {
    return (
      <div>
        <button
          style={{ color: this.state.themeColor }}
          onClick={() => this.handleSwitchColor}
        >Red</button>
        <button
          style={{ color: this.state.themeColor }}
          onClick={this.handleSwitchColor}
        >Blue</button>
      </div>
    )
  }

ask:

code, but how do you pass parameters to this function in this way?

this.handleSwitchColor() //
