Adding a swatche to a User Defined Library

I will try libraries from now on, many thanks.

Thanks. I probably didn't make things clear. I am drawing a map, I have a library which I use for all my maps for this book. I have about a dozen colours. Now I find I need another blue, I want to add this to my atlas library.

Now, with a document open I can set up rectangles, colour them from the library, drag them into the default library, then I can add the new one and save to overwrite the user defined one, voila I have the new colour in my library. I just think there must be an easier way? No?

Thanks for taking the time to look.

Open the swatch library as if it was a regular AI file. It should appear blank, but your swatches will be present in the swatch panel. Add a swatch there, then save and overwrite the old swatch library file from the swatch panel.

Swatch/graphic style/brush libraries etc. are just regular AI files with everything else stripped out.

If I understand your question, you want to update another document with the swatches that you add to a different document? Have you taken a look at CC Libraries? This makes it easy to manage swatches in one central location and you can easily load them into other documents. If you don't want to use CC Libraries, you can select the swatches from one document and export them as an .ase file (Adobe Swatch Exchange) using the panel menu of the Swatches panel. Then in the other document, you just load them in.
