how to style disabled antd picker

I need to apply a custom style to the disabled the antd range picker.

I have added className to the component but the style isn’t changing.

                        <RangePicker
                          className="my-range"
                          allowClear={false}
                          bordered={true}
                          format="HH:mm"
                          style={{ width: "100%" }}
                        />

Styles Css: (need to change color of the text in the box)

.ant-picker-disabled.building-ophrs-range {
  background-color: #ffffff;
  .ant-picker-input.ant-picker-input-active {
    color: #224cc0;
  }
}
