This looks very much like the True Colours test that was popular here 10 - 15 years ago. I like it, in that I found I got the same results consistently, rather than the variation in results I saw with Myers-Briggs.
The categories were:
Orange - spontaneous, creative, fun-loving, rule-breaking, rebellious, leisure-seeking
Green - rational, scientific, data-driven, head rules the heart
Blue - warm, kind, emotional
Gold - conscientious, duty-driven, compliant, reliable
I consistently scored very high in Gold, tied pretty much with moderate Green and Blue scores, and scored the minimum possible in the Orange category. This is probably typical of Brit-descended repressed male boomers.
Some of the literature then gets into how we (of a given dominant personality type) see ourselves, how members of the other groups see us, and our strengths and weaknesses.
However, Dr Brian Little's 'Big 5' personality traits (OCEAN - openness, conscientiousness, extraversion, agreeableness, and neuroticism) are now considered to be the gold standard.
