This is rather simple using standard DOM:

function changeBgr(element, color) {
document.getElementById(element).style.backgroundColor = color;
document.form1.field1.value = color;
}

The cell (or div) you're changing should have the ID set:
<td id="first"> or <div id="second">,

and the text field is named "field1" and placed inside form1:

<form name="form1">
<input type="text" name="field1">
</form>

The function should be called like this:

<a href="#" onclick="changeBgr('first', '#339966')" title="click to change backgr color"><img src="transp.gif" width=... height=... border="0"></a>
