Would it be possible (or desirable) to have a CYMK GrayToColor in addition to the RGB GrayToColor? If you have more than 3 dyes, you’ll not be able to represent all colors effectively.
I will add it to the feature requests and post here when it’s released.
We will have a CMYK option for the next release but in the meantime, I’m attaching a pipeline which does the equivalent operation. It uses an image from the ExampleFly data set available on our webpage.

For those who are interested: The latest version of CellProfiler (available from our website) has improvements to the GrayToColor module which allow the user to specify whether grayscale images are to be combined as RGB or CMYK.
