The Color Code Personality Profile also known as The Color Code or The People Code is a personality test designed by Taylor Hartman.^[1] Despite being widely used in business and other fields, it is considered a pseudoscience.^[2]

The Hartman Personality Profile is based on the notion that all people possess one of four driving "core motives".^[3] The Color Code is based on four types of personality, identified by color: Red, (motivated by power); Blue, (motivated by intimacy); White, (motivated by peace); and Yellow, (motivated by fun).^[4] Although demographic groups vary, Hartman suggests that Reds comprise 25% of the population; Blues 35%; Whites 20%; and Yellows 20%.^[5] There is no scientific proof to support these claims.^{[6] [failed verification]}

The Hartman Institute and its many subsidiaries offer "coaches" to businesses seeking to improve interpersonal relations, for career counselling, or to collect data for use in hiring practices.^[7] The test informally^{[clarification needed]} passes most psychometric measures of reliability and face validity,^[8] but this may be attributed to the open predictability of the test.^{[citation needed]} The criteria are likely self-fulfilling to an extent. Although internal and small sample corporate-sponsored data have been reported,^[9] no peer-reviewed studies of the psychometric value of the test exist.
