  In color picker I use:
  
    // formula for luminance according to 
https://www.w3.org/TR/2008/REC-WCAG20-20081211/#relativeluminancedef
    
                            var a = [color.r, color.g, color.b].map(function 
(v) {
                                return (v <= 0.03928) ? v / 12.92 :
                                                        Math.pow( ((v + 0.055) 
/ 1.055), 2.4 );
                            });
    
                            return a[0] * 0.2126 + a[1] * 0.7152 + a[2] * 
0.0722;
