Do you support Pantone Colors?

Yes, but with some limitation.

You can manually specify a Pantone Color name and its CMYK value in the Color window, by clicking “New” button to create a Pantone color.
Then, set it as a “Spot” color and assign a Pantone color name in the name field as shown below.

You can create multiple Pantone color swatchs in the MathMagic Color window – Application-wide Color List.
The current versions do not support any Pantone swatch list yet.
