I have a problem. I wish to flash (or blink) text from yellow to grey, but I would like the yellow text to remain displayed longer than the grey text.

The code that I have works for an equal duration for each color.

```
function flashtext(ele,col) {
var tmpColCheck = document.getElementById( ele ).style.color;

   if (tmpColCheck === 'grey') {
       document.getElementById( ele ).style.color = col;
   } else {
       document.getElementById( ele ).style.color = 'grey';
   }
 } 

setInterval(function() {
    flashtext('flashingtext','yellow');
}, 700 ); //set an interval timer up to repeat the function

```

Any ideas?
