Although this is a JS solution, it could be modified to perl. The reason its in JS is that by sending the full table out (as you'd do with a perl solution), you're outputting a lot more data than is needed.

I use the following javascript to let people select a color in a form text field. The text field lets them type a color if they know it, or they click a button to choose one:

function choosecolor(form, name, title) {
        colorWindow=window.open("about:blank","colorWindow","width=400
+,height=120,resizable=yes")

        colorlist = new Array('00','33','66','99','CC','FF');
        colorWindow.document.write("<table border=0 cellpadding=0 cell
+spacing=0>");
        colorWindow.document.write("<tr><td colspan=3 align=center><fo
+nt face='arial,helvetica,sans' size=3><b>" + title + "</b></td></tr>"
+);
        colorWindow.document.write("    <tr>");
        for (var rcolor in colorlist) {
            colorWindow.document.write("        <td>");
            colorWindow.document.write("            <table border=0 ce
+llpadding=0 cellspacing=2>");
            for (var gcolor in colorlist) {
                colorWindow.document.write("                <tr>");
                for (var bcolor in colorlist) {
                    colorWindow.document.write("                    <t
+d bgcolor='#" + colorlist[rcolor] + colorlist[bcolor] + colorlist[gco
+lor] + "'><a href=\"javascript:window.opener.document." + form + "." 
++ name + ".value='#" + colorlist[rcolor] + colorlist[bcolor] + colorl
+ist[gcolor] + "'; self.close()\"><img src="./images/clearpixel.gif' w
+idth=8 height=8 border=0></a></td>");
                }
                colorWindow.document.write("                </tr>");
            }
            colorWindow.document.write("            </table>");
            colorWindow.document.write("        </td>");
        }
        colorWindow.document.write("    </tr>");
        colorWindow.document.write("</table></font><form><input type=b
+utton value=' Cancel ' onclick='self.close()'></form></center>");

Which works from a form like this:

<form name=colorpicker>
Enter a color:<input name=color type=text><input type=button value="Pi
+ck" onclick="choosecolor('colorpicker', 'color', 'Pick a color for no
+ reason at all')">
</form>

Hope this helps ... please forgive the lack of a perl solution, but note the above reasoning for it.
