判断两色素颜色的相似度

colors.js

var Distance = 150; //设置阀值 结果和该值比较，如果小于它就代表相似

//color1 = {r:xxx,b:xxx,g:xxx};
function Compared(color1,color2){
  let _liked = false;
  let _r = color1.r-color2.r;
  let _g = color1.g-color2.g;
  let _b = color1.b-color2.b;
  
  if(Math.sqrt(Math.pow(_r,2)+Math.pow(_g,2)+Math.pow(_g,2))<Distance){
    _liked = true;
  }
  return _liked;
}
