如何在blueprintjs中自定义颜色？

import { Button } from "@blueprintjs/core";
import "@blueprintjs/core/lib/css/blueprint.css";

import React from "react";
import { Button } from "@blueprintjs/core";
import "@blueprintjs/core/lib/css/blueprint.css";
import "./customStyles.css"; // 引入自定义样式文件

const CustomButton = () => {
  return (
    <Button className="custom-button" intent="primary">
      Custom Button
    </Button>
  );
};

export default CustomButton;

.custom-button {
  background-color: #ff0000 !important; /* 自定义按钮背景颜色 */
  color: #ffffff !important; /* 自定义按钮文字颜色 */
}
