If you want to transfer your color swatches saved in your OS X color picker to another mac here’s how:

Step 1;

On the mac computer with the swatches you want to copy, go to your home account -> Library -> Colors folder. Here you’ll find a file called: “NSColorPanelSwatches.plist.”

Step 2;

Copy this file into the same location on your other mac computer and when you launch your color picker all your original swatches should be there.
