• 提取颜色
• 修圆最终颜色

const mixColours = (color1, color2, color3, percentage1, percentage2, percentage3) => {
    const red1 = parseInt(color1.slice(1, 3), 16);
    const green1 = parseInt(color1.slice(3, 5), 16);
    const blue1 = parseInt(color1.slice(5, 7), 16);
  
    const red2 = parseInt(color2.slice(1, 3), 16);
    const green2 = parseInt(color2.slice(3, 5), 16);
    const blue2 = parseInt(color2.slice(5, 7), 16);
  
    const red3 = parseInt(color3.slice(1, 3), 16);
    const green3 = parseInt(color3.slice(3, 5), 16);
    const blue3 = parseInt(color3.slice(5, 7), 16);
  
    const red = Math.round((red1 * percentage1 + red2 * percentage2 + red3 * percentage3) / (percentage1 + percentage2 + percentage3));
    const green = Math.round((green1 * percentage1 + green2 * percentage2 + green3 * percentage3) / (percentage1 + percentage2 + percentage3));
    const blue = Math.round((blue1 * percentage1 + blue2 * percentage2 + blue3 * percentage3) / (percentage1 + percentage2 + percentage3));
  
    return generateHex(red, green, blue);
};
