Color mapping is a method of assigning different speed and power settings to different parts of an image based on colors.

For example, you could make all red pixels engrave at a much higher power than blue pixels, which would make the red areas of your design much more pronounced.

This works with both engravings and cuts, so you could have a single job cut through some areas with stronger settings and use weaker settings to create outlines or perforations in other areas.
