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

getAntdSerials(color: string): string[] {
    const lightCount = 9;
    const divide = 10;
    // 淡化（即less的tint）
    let lightens = new Array(lightCount).fill(0);
    lightens = lightens.map((_, i) => client.varyColor.lighten(color, i / divide));
    const colorPalettes = generate(color);
    const rgb = client.varyColor.toNum3(color.replace('#', '')).join(',');
    return lightens.concat(colorPalettes).concat(rgb);
  },
  changeColor(color?: string): Promise {

const lightens = new Array(9).fill().map((t, i) => {
      return client.varyColor.lighten(color, i / 10)
    })
    // colorPalette变换得到颜色值

    lightens = lightens.map((_, i) => client.varyColor.lighten(color, i / divide));
    const colorPalettes = generate(color);

    lightens = lightens.map((_, i) => client.varyColor.lighten(color, i / divide));
    const colorPalettes = generate(color);

lightens = lightens.map((_, i) =>
      client.varyColor.lighten(color, i / divide),
    );

    lightens = lightens.map((_, i) => client.varyColor.lighten(color, i / divide));
    const colorPalettes = generate(color);
