PCPT was authored by Dawn L. Billings for use in her family-systems private practice in 2002. Dawn felt limited by the traditional four quadrant tests and wanted to create a tool that would provide her with more specific information she felt she needed, while at the same time, be simpler for her clients to complete and understand.

Dawn earned a Master's degree in Clinical Psychology while focusing on Organizational Psychology for her doctorate studies. She quickly realized that whether she was working with couples and families who were struggling because of a break down in respect, communication, and understanding, or attempting to help different departments within a company communicate with, and work together more effectively, similar communication problems were consistently evident.

By helping her clients and the members of her audiences learn to understand how different personalities might see the world through different colored lenses she created a fun, entertaining, non-threatening, easy to use this powerful insight tool to benefit individuals, couples, families, children, churches, corporations and organizations around the world.

Personality expert, Dawn Billings developed the Primary Colors Personality test to help people gain insight into their personality tendencies, as they also gained insight into the personality tendencies of the people they cared about, in different contexts in their lives. Dawn began to see that if her clients or audience members understood the six differing personality color tendencies that they were better equipped to communicate more positively, powerfully and effectively with others in their lives.
