The following example creates a clickable color and gray palettes.
Note: you must have a pngs directory at the document root level.
<script language="JavaScript">

 var coRed=127;coGreen=127;coBlue=255; // Original color
 
var Hex=new Array("0","1","2","3","4","5","6","7","8","9","A","B","C","D","E","F");

function rgb2hex(cRed,cGreen,cBlue){
cColor=Hex[Math.floor(cRed/16)]+Hex[cRed%16]+Hex[Math.floor(cGreen/16)]+Hex[cGreen%16]+Hex[Math.floor(cBlue/16)]+Hex[cBlue%16];
return cColor;
}
 
function ShowColor(cColor){
with (document){
 // Do whatever you have to do here
  }
 };
 
 function plttClick(cRed,cGreen,cBlue){
   // Change the color
  coRed=cRed;
  coGreen=cGreen;
  coBlue=cBlue;
   // Replace the following line with your own code
  alert(cRed+','+cGreen+','+cBlue)
 }
 
 function plttOver(cRed,cGreen,cBlue){
  ShowColor(rgb2hex(cRed,cGreen,cBlue));
   // Add you own code here
  self.status='Red: '+cRed+' / Green: '+cGreen+' / Blue: '+cBlue;
 }
 
 function plttOut(){
   // Restore original color
  ShowColor(rgb2hex(coRed,coGreen,coBlue));
   // Add you own code here
  self.status='Click on the color of your choice';
