A simple search yields the following as the first result:

https://community.ptc.com/t5/PTC-Education-Forum/How-to-Create-STEP-file-with-Colors-from-Creo-Parametric/td-p/10975 

This tells how to output a STEP file in a format that supports colors. There are a number of versions of STEP file, apparently with different capabilities.

You'll have to figure out how to use the functions you are implementing to output a file with the settings detailed in the discussion. Hopefully the toolkit stuff you are using has enough descriptive comments for you to do so.
