[U]How to setup

Step 1: Place JavaScript below in your HEAD section
JavaScript

<script type="text/javascript">
// Created by: Joseph Myers | http://www.codelib.net/
// This script downloaded from www.JavaScriptBank.com

function colorscale(hexstr, scalefactor) {
/* declared variables first, in order;
afterwards, undeclared local variables */
var r = scalefactor;
var a, i;
if (r < 0 || typeof(hexstr) != 'string')
return hexstr;
hexstr = hexstr.replace(/[^0-9a-f]+/ig, '');
if (hexstr.length == 3) {
a = hexstr.split('');
} else if (hexstr.length == 6) {
a = hexstr.match(/(\w{2})/g);
} else
return hexstr;
for (i=0; i<a.length; i++) {
if (a[i].length == 2)
a[i] = parseInt(a[i], 16);
else {
a[i] = parseInt(a[i], 16);
a[i] = a[i]*16 + a[i];
}
}

var maxColor = parseInt('ff', 16);

function relsize(a) {
if (a == maxColor)
return Infinity;
return a/(maxColor-a);
}

function relsizeinv(y) {
if (y == Infinity)
return maxColor;
return maxColor*y/(1+y);
}

for (i=0; i<a.length; i++) {
a[i] = relsizeinv(relsize(a[i])*r);
a[i] = Math.floor(a[i]).toString(16);
if (a[i].length == 1)
a[i] = '0' + a[i];
}
return a.join('');
}

function showrainbow(f) {
var colorcell, hex, i, nhex;
hex = f.orig.value;
hex = hex.replace(/\W/g, '');
nhex = colorscale(hex, f.scalef.value-0);
if (nhex != hex) {
f.outp.value = nhex;
colorcell = document.getElementById('origcolor');
i = document.getElementById('newcolor');
colorcell.style.background = '#' + hex;
i.style.background = '#' + nhex;
for (i=0; i<256; i++) {
colorcell = document.getElementById('colorcell'+i);
nhex = colorscale(hex, i/(256-i));
colorcell.style.background = '#' + nhex;
colorcell.nhexvalue = nhex;
}
}
}
</script>

Step 2: Copy & Paste HTML code below in your BODY section
HTML

<div style="width: 400px;">
<form>
<p>
Original color: <input type="text" name="orig" value="339990"><br>
Scale factor: <input type="text" name="scalef" value="4"><br>
<input type="button" value="Output" onclick="showrainbow(this.form)">
<input type="text" readonly name="outp" style="border: none;">
</p>
</form>

<table width="150">
<tr>
<td width="50%" height="50" id="origcolor">Original</td>
<td width="50%" id="newcolor">New</td></tr>
</table>

<table cellpadding="0" cellspacing="0">
<tr>
<script type="text/javascript">
for (i=0; i<256; i++)
document.write('<td width="10" height="50" id="colorcell', i, '" onclick="document.forms[0].outp.value = this.nhexvalue"></td>');
</script>
</tr>
</table>

With MS Frontpage designing becomes very much easy. But the generated code is not much clear to the designer or developer. So it does not provide much flexibility to your code. With Dreamweaver the generated code becomes easier to understand and it also provide reference manuals for scripting.
