Importing a Photoshop Image and keeping the color scheme

I understand the character needs to be cut up into layers and that I am able to do this process in photoshop.

I am however more familiar with toonboom and I enjoy the ease of use I have grown accustom to with the contour editor and such.

my question is I have both black and white and color versions of my characters below is a sample.

I import the black and white version and then what I do is I cut up the character in toonboom and then I use the paint option in photoshop to match the color scheme created by my animator.

I want to know how to use the color scheme in toon boom with my character and not to use the color schemes I create in toon boom.

anyone have any ideas???
