This will add a color selector:

javascript:for(var i=0;i<6;i++){for(var j=0;j<6;j++){for(var k=0;k<6;k++){txt = '#'+'0369cf'.substr(i,1)+'0369cf'.substr(j,1)+'0369cf'.substr(k,1);$('.tools').append("<a href='#drawing' data-color='" + txt + "'style='width: 5px; height: 5px; padding: 0; spacing: 0; background: " + txt + ";'></a> ");}}}
