Spot colors are a type of color that is used to add interest and brightness to your illustrations. Spot colors can be used in any drawing or painting project, and they can be used to create a variety of effects. Spot colors are created by adding a color to the bottom of each pixel in an image or drawing. This color is then used as the base for all other colors in the image or drawing. Spot colors can be created using any color palette, but they are most commonly used in Adobe Illustrator. When creating spot colors, you will want to use a light blue, light green, and dark green palette.
