About Us

Hi, I'm Dewey Sadka, the CEO of Dewey Color System. My success, as the owner/CEO of one of the nations largest and fastest growing staffing companies, was in part due to one question, “What do you enjoy doing?” Other assessments only scratched the surface, just didn’t predict passion.

After 25 years of hard work and millions invested, it’s my hope that you will use the Dewey Color System to choose a beautiful life.

WHAT IS IT?

The Dewey Color System® is a non-language career evaluation — setting it apart from ALL other personality testing instruments.
It’s a multi-patented system that uses color preference to calculate 27 different personality types and over 1,000 career choices.
A proven 2-minute, free online test with a viral component that builds page-per-views, revenue, and a community.

WHERE DID IT COME FROM?
