如何从十六进制颜色字符串中获取颜色

function getColorFromHex(hexColor) {
  // 解析十六进制颜色字符串
  const red = parseInt(hexColor.substr(0, 2), 16);
  const green = parseInt(hexColor.substr(2, 2), 16);
  const blue = parseInt(hexColor.substr(4, 2), 16);

  // 创建颜色对象
  const color = {
    red: red,
    green: green,
    blue: blue
  };

  return color;
}

// 示例用法
const hexColor = "FF0000"; // 红色
const color = getColorFromHex(hexColor);
console.log(color); // 输出：{ red: 255, green: 0, blue: 0 }
