Directions:

Simply download yuicolorpicker.zip, and open up "demo.htm" using any text editor for the code to insert onto your page.
Customization

While this script references multiple .js files, to integrate the color picker with your form in the fashion above, you do not need to be bothered with modifying any of these files. Instead, there are only two changes you need to make to the code of "demo.htm" to integrate the color picker into your page:

1) Locate the code:

ddcolorposter.fillcolorbox("colorfield1", "colorbox1") //PREFILL "colorbox1" with hex value from "colorfield1"
ddcolorposter.fillcolorbox("colorfield2", "colorbox2") //PREFILL "colorbox1" with hex value from "colorfield1"

These two lines are used to prefill the color boxes to the right of the form fields in question with the color currently inside the field when the page first loads. Without this code, when your page loads, the color boxes will not be initially filled with the color values inside the form fields.

There are two fields in the demo, hence two lines. The first parameter of fillcolorbox(), "colorfield1", should be the ID of the form field, while the second parameter, the ID of the matching color box. See below for more information.

2) Locate the code:

<form>
# <input type="text" id="colorfield1" onFocus="ddcolorposter.echocolor(this, 'colorbox1')"> <span id="colorbox1" class="colorbox">____</span>

# <input type="text" id="colorfield2" onFocus="ddcolorposter.echocolor(this, 'colorbox2')"> <span id="colorbox2" class="colorbox">____</span>
</form>

This code demonstrates how to integrate the color picker with any form field on your page.

The trick here is to add this after a fields ID - onFocus="ddcolorposter.echocolor(this, 'colorbox1')

for each field you want the color to be selected  name them sequentially i.e. colorbox1, colorbox2 etc.

This is the part of the code to identify the proper box :

ddcolorposter.fillcolorbox("fieldname", "colorbox1") //PREFILL "colorbox1" with hex value from "colorfield1"

This is how we set up one field:

<input type="text" name="page_border_color_<?php echo $cnt1; ?>" id="page_border_color_<?php echo $cnt1; ?>"  onFocus="ddcolorposter.echocolor(this, 'colorbox6')" value="<?php echo ($row_rstbl_ppcart_settings['page_border_color']); ?>" size="7" maxlength="6" /><span id="colorbox6" class="colorbox">____</span> New Selection

This :

<span id="colorbox6" class="colorbox">____</span> New Selection

Just shows you what color you've just selected

This we added to show the current color

<table width="25px" height="20px">
                            <tr>
                              <td bgcolor="#<?php echo $row_rstbl_ppcart_settings['page_border_color']; ?>"></td>
                            </tr>
                          </table>
