But what if you want to work on the project on more then one computer? How do you transfer those swatches from one computer to the other? After digging around, I found that the swatches were stored in a preference file in your home folder:
~/Library/Colors/NSColorPanelSwatches.plist
Just copy this from one computer to the similar location in the other, and you have transfered your Color Panel swatches.
Note: If you already have swatches setup on the target computer, that file will already exist. If you want to be able to go back to those swatches, make sure you back that file up somewhere else first.
