You can also create other colors by mixing two or more of the above colors together. Next, you need to decide what type of color you want. There are three types of color: primary, secondary, and tertiary. Primary colors are the most basic and most common in Illustrator. They are black, white, and gray. Secondary colors can be created by mixing primary and secondary colors together. tertiary colors can be created by mixing any two primary or secondary colors together to create a new color. Once you have decided on your color, it’s time to start creating your illustrations!
