Now that you know all about color perception and color printing, it’s time to get down to the process of specifying and applying colors in your InDesign publication.
InDesign has two basic methods for working with color: unnamed colors and color swatches. What’s the difference? Both unnamed colors and color swatches can change the appearance of an object’s fill or stroke, but swatches establish a relationship between the object and the named color swatch. Change the definition of the color swatch, and the color of all of the objects you’ve applied that swatch to will change as well.
