By default, the name of a process color swatch is derived from the values of the color’s components. For example, if you create a red process color using 10% cyan, 75% magenta, 100% yellow, and 0% black, its swatch will be named C=10 M=75 Y=100 K=0 by default. This makes it easier to identify the composition of process colors.
By default, the name of a process color swatch automatically updates when you change its CMYK values; you can switch this option off or on for individual swatches as needed. As with any swatch you define, you can change the name of a process color swatch at any time.
To let InDesign rename the swatch when you adjust its CMYK percentages, make sure that the Name With Color Value option is selected.
To rename a swatch when you adjust its CMYK values, make sure that the Name With Color Value option is deselected.
