Desaturate

Phantasm Desaturate is a live effect/filter that equalizes color channels. By default, it is the same as using the Hue/Saturation effect with a Saturation value of –100. Note that like Photoshop’s Saturation adjustment, the lightness of the original color is not necessarily preserved. For example, 100% Yellow and 100% Magenta will both be adjusted to a value of 50% Cyan, 50% Magenta, and 50% Yellow.

As a live effect, it is accessible through the main menu, under Effect > Phantasm > Desaturate. It can also be applied directly from the Appearance panel using the “Add New Effect” button at the bottom of the panel, or through the Phantasm panel (see Phantasm: Panel).

After applying the live effect using the menu item (or when clicking on the existing effect in the Appearance panel to edit it), the parameters dialog will appear:

1. Gray Tone

Available only if the document is in CMYK color space. It ensures that the altered color is only composed of Black ink, and it equivalent to using the Hue/Saturation effect in Colorize mode with a Saturation value of 0.
