Setting Up the CutContour

Hello,

I am using a CorelDRAW tutorial to set up my CutContour as a magenta color on my side-bar, but when I get to the step where I click the black arrow and then click 'Edit Color' from the dropdown menu, the option for edit color is greyed-out for me. I am unable to complete the process to create a cut-contour.

Is there another way to set up the Cut Contour in CorelDRAW 2017, or a way to get around why my option is unavailable?

Thank you.
