Spot color is a feature in Illustrator that lets you add a specific color to a selected area of the document. You can use spot color to add a pop of color to an image, or to help you distinguish different elements in your design. To use spot color in Illustrator, first select the area of the document where you want to apply the color. Then click on the Spot Color button (the three dots in the toolbar). The Spot Color dialog box will open. In this dialog box, you can choose from a variety of colors, or you can click on the eyedropper icon to sample a color from your document. Once you have selected your desired color, click on OK to apply the color to the selected area of your document. ..
