In the course you will learn how to use the Phantasm live effects to easily control hue, saturation, brightness, contrast and add halftones to your artwork. When working with embedded images, you can add many effects that are native to photoshop, directly to the images in illustrator without the need of going to photoshop to add the effects.

Also included in this plugin are color balance controls, levels adjustments, curves, desaturate, and shift to color. These are incredible tools that allow me to easily modify colors of artwork and everything in non-destructive which means I can easily go back to the original colors, or expand the artwork and have the colors permanently changed to the new colors.
