const less = require('theme-color-switch');
const colorSource = require('!raw-loader!./public/color.less'); // theme file content which generate by theme-color-generator
less.render(
   colorSource,
   {
       modifyVars: {
           '@theme-color': '#0035ff' // the variables in theme file which you want to change
       },
   },
   function(e, output) {
      if (e) {
          console.error(`Failed to update theme`);
      }
      if (output && output.css) {
          addCSS(output.css);
      }
   }
);

Note: You need to generate `color.less` file with theme-color-generator ( as `color.js` in example ) first, then toggle color with this package as `Theme.js` in example

Now you can change colors by modify less avriables as the example

如只想使用主题切换的，上面的内容就已完成。

颜色函数：想要用js执行less颜色函数实时转化颜色的，请往下看（详细说明请访问less官网）。

返回Color对象的可以使用toCSS()属性来获取输出值。也可以作为下一个函数的颜色参数。
返回Dimension对象的可以作为number类型传给下一个函数。

使用示例

import { shade, tint, fade } from 'theme-color-switch';

let shadeColor = shade('#007fff', '50%').toCSS();
let fadeAndTintColor = fade(tint('#007fff', '30%'), '10%').toCSS();
