So, are you in fact saying there is a way I can instruct Artist 1 on how to share her swatches to my computer WITHOUT her having to send me a large amount of old files that I would have to download and open copy one by one each of her colors? |
Yes, swatches are user defined and are not part of the application. You can also access color libraries which are similar to plugins but are also not hardwired into the application. The Pantone libraries have to be updated separately from the application like any plugin.
Artist 1 can export any number of swatches via the Save Swatches... dialog and you can load them via Load Swatches... Here I'm showing my Swatches panel with no documents open. Every document I create starts with these swatches. I can add or delete swatches as needed once the document is created and the new swatches list will be specific to that document:

You can also drag and drop swatches between documents.
Get Artist 1 to gather the colors into one document and save them out to an .ASE file. If you close all documents and load that .ASE file, the swatches will be added to your default swatches list.
