[jQuery] Color animation on textarea

[jQuery] Color animation on textarea


I am trying to apply a color animation to a textarea when text is
appended to it.
Here is what I have...
HTML:
<textarea id="reply"><textarea>
JQ:
$("#reply")
        .animate({backgroundColor:'red'}, "fast")
        .append("\n"+insertText+"\n")
        .animate({backgroundColor:'white'}, "fast");
This is not working, what am I mssing? The color does not change at
all?
TIA
