If you need color assistance then yes this can help with pretty much any site editing system from HTML, VSD and Wordpress or Joomla. Basically it's a color code helper and schemer to create color schemes for your sites. I use it all the time, mostly just to find a color I like and then get the code for it.
If you are in need of a tool for that, then this program will work great for you. If you're not in need of it then it wouldn't pay to get it. Hope that helps
