How do get the label id or label name of a filed's label?

Question

Hello everybody,
I need your help for getting the name of id of label, this label belongs to a field in a form.
When I create my javascript's function I could manipulate the visibility of a field with the next sentence:
document.getElementById("P1_NAME_OF_FIELD").style.visibility = "visible";
but I do not know to do the same thing with its label:
Also, I have tried with the parentnode javascript attribute, this is because getting the parentnode ( a tag of TD ) but I don't have a good result.
document.getElementById.parentNode.parentNode.style.visibility = "visible";
I write twice parentnode because I found in the code that the label and the field are like this:
<tr>
<td> label </td>
<td> text field </td>
</tr>
The first parent node is TD and the second corresponding to TR.
After that I edit the item, in the label's part I wrote in Label:
<div id="ID_LABEL" name="ID_LABEL" style="visibility:hidden"> Label </div>
This was for assigning the id to the label and with this to identy easily.
and in the element's part I wrote in 'HTML Table Cell Attributes'
style = "visibility:hidden"
And in the javascript function I wrote the next:
document.getElementById("P1_NAME_OF_FIELD").style.visibility = "visible";
document.getElementById("ID_LABEL").style.visibility = "visible";
With this I could manipulate the visibility but the problem is that the font size of is not the same with the others labels.
Could you help me with this problem?
What and how do I must do in apex?
Could you send me a page with relationated examples with this problem?
Thank you.
Best Regards.

Long story short: A ColorModel is not a Color. It is an object containing information about how the colors in an object are described... or something like that.
Component.getForeground() is probably want you want. It returns a Color object.
