How to Make a New Illustrator Template with Custom Swatches

1. Make your document with your preferred swatches. Save it to your desktop and close it.
2. Move it to: Applications > Adobe Illustrator 2025 > Cool Extras > en_US > Templates > Blank Templates
3. When you need a document with those swatches, go to File > New from Template and choose that template.
4. If you need other elements, like symbols or graphic styles, you can also add those to your template.
