I just wrote a tut for folks that want to use Adobe's free Kuler website (great for creating color swatches) and then getting those swatches into the system palette, ie. accessible to iWeb, Final Cut Pro, etc. I use Kuler before I begin any iWeb to set my color scheme.
See it here:http://library.creativecow.net/gaton_jiggy/adobe-kuler/1
Don't create garish titles anymore, see that tut to find out how you can find a contrasting color without picking up a color wheel!
Anyway, hope you all find this of use. Happy Teej...
