I am looking forward to customizing the **Raphael JS Pie Chart**...

Here is the code,
<http://jsfiddle.net/kcQbe/>

I have set 4 categories in it...

1st of all i want the change the color fills or path's color on every category defined separately in JavaScript, for example like categories are looping into array which is called as `data = [90, 90, 90, 90]` here 90 is the degree at which we are defining the category's angle like that i want color should also b define separately and similar to that... 
may be like this `fill = ["#000","#ccc","#ddd","#eee"]`
I could be wrong for that idea i am not sure...

Also on clicking it the color changes, i want that the color should remain the same as it is before clicking it...

Can anyone help it???
