I have known about the color quiz based in the work of Dr. Max Lascher  for a number of years.  This instrument is used worldwide, most notably
in Europe, by psychologists, doctors, government agencies, and universities to screen
their candidates. Since the 1950's the instrument has been given to hundreds of thousands
of people. 

Now psychiatry professor Lange has come along with something that looks very similar: Color Career Counselor.
While I tried to do the interactive test online, the two browsers I used: Firefox and Safari on Mac didn't want to give me my final results – nor did it send me the results when I gave my email.  It was rather disappointing but perhaps you might fair better.  Apparently, according to Inc. an analysis of some 900 CEOs' results shows they like magenta — and
are less dominant and confident than the rest of the population.

Career Path claims that their  Color Career Counselor
is the world's first non-language test to define occupational
interests. It uses color preference to determine successful career
paths. The test is based on the multi-patented Dewey Color System, which is the world's only scientifically validated color-based personality test – published in the North American Journal of Psychology. The Color Career Indicator 4.0, provided by Dewey Color System,
is an extensive evaluation that identifies "Your Most Fun Careers" from
among more than 1,000 occupations, with record-breaking accuracy. A
specific, ranked list of your top jobs is provided to you, along with
additional information to assist you in your career exploration.

Test color can generate over 50 million different answers, each one written by an artificial intelligence engine for every test. Our symbolical rules are in conformance with the Freudian topics and the C.G. Jung's typology.  They all have been validated by a group of 800 people and by over 1 800 000 on line tests.

For those with reading or language challenges this might be an option. I have no idea how valid these assessments are or if you will find them enlightening or just entertaining.  All the ones I have listed are free so there is little to loose.  I would recommend trying all of them yourself and doing some comparisons.  If you do not see some correlations or comparisons, I would suggest not using them. 

Your experiences would be appreciated in the comments.
