I've completely switched over to using the Import method.
I manipulate them using a text editor, then paste the result back.
The benefit for me is that I can have one standardized color pallet pasted in every dashboard.

Even if a specific Dashboard doesn't use an Outlet, for example, the color is there should I ever change my mind
OH. I pasted JUST the snippet having to do with customColor. It ends just before the words: "name": with your dashboard's name.
