EC,
Here is a website that I use for some different colors for caps, jerseys and logos. I too use Justafan's awesome software programs. In order to change a color you can either click and drag the little tool next that looks like a medicine dropper to the color you want or click on the color box and it will bring up a color dialogue box to choose a color.
Here is that Color Table site I use:

As always, if ya need more help, just holler.
