          onChange={this.handleChange("value")}
          name="value"

              </option>

You have to override the <option> 's backgroundColor: https://codesandbox.io/s/509n6o1v1l

You can look at the implementation to look at the CSS rule you need to override: https://github.com/mui-org/material-ui/blob/10b9d6aef53d20ba4e368f40c9acbb7b05c5c855/packages/material-ui/src/NativeSelect/NativeSelect.js#L48-L50
