Max Lüscher

Besides research, teaching and practicing psychotherapy in Basel, Lüscher worked for international companies, amongst other things giving color advice.

This test used color cards to determine the current emotional state of the test-taker.

The test-taker chooses the card color they like best and then orders the rest from most-preferred to least-preferred.

[3] Lüscher argues that the subject's choice of color shows the state of their psychosomatic and emotional status and how they feel about themselves.

Lüscher relates to his four fundamental colors to the following fundamental categories: A 1984 comparison of the Lüscher color test and the Minnesota Multiphasic Personality Inventory found little agreement between the two tests, prompting the authors to urge cautious use of the former.
