In this tutorial, I show you how to create a new swatch from a photoshop image or document. I also show you how to save it to your library.
First step is you want to go to your eyedropper tool. Then you select the colour that you want to use. Left click on it, and at the top you'll see the colour.
Next, you want to go to your swatch panel. Now go to the hamburger menu, then click the hamburger menu. Then you can add the swatch to your current library, nice and easy!
