How to use the webpack-theme-color-replacer.varyColor function in webpack-theme-color-replacer

const getAntdSerials = (color: string) => {
  const lightNum = 9;
  const devide10 = 10;
  // 淡化（即less的tint）
  const lightens = new Array(lightNum).fill(undefined).map((_, i: number) => {
    return ThemeColorReplacer.varyColor.lighten(color, i / devide10);
  });
  const colorPalettes = generate(color);
  const rgb = ThemeColorReplacer.varyColor.toNum3(color.replace('#', '')).join(',');
  return lightens.concat(colorPalettes).concat(rgb);
};

var lightens = new Array(9).fill().map((t, i) => {
    return ThemeColorReplacer.varyColor.lighten(color, i / 10);
  });
  // 此处为了简化，采用了darken。实际按color.less需求可以引入tinycolor, colorPalette变换得到颜色值

const lightens = new Array(lightNum).fill(undefined).map((_, i: number) => {
    return ThemeColorReplacer.varyColor.lighten(color, i / devide10);
  });
  const colorPalettes = generate(color);

const lightens = new Array(lightNum).fill(undefined).map((_, i: number) => {
    return ThemeColorReplacer.varyColor.lighten(color, i / devide10);
  });
  const colorPalettes = generate(color);

const lightens = new Array(lightNum).fill(undefined).map((_, i: number) => {
    return ThemeColorReplacer.varyColor.lighten(color, i / devide10);
  });
  const colorPalettes = generate(color);

var darkens = new Array(6).fill().map((t, i) => {
    return ThemeColorReplacer.varyColor.darken(color, i / 10);
  });
  return lightens.concat(darkens);

const lightens = new Array(lightNum).fill().map((t, i) => {
    return ThemeColorReplacer.varyColor.lighten(color, i / devide10);
  });
  const colorPalettes = generate(color);
