I remember taking a communications course that taught color personalities, it seemed very basic to me at the time and I didn't take it that seriously considering I studied socionics before. It just struck me as a lamer version of the Enneagram.
Here's a basic overview of the color personalities:
Green: Intellectual
Blue: Creative/Social
Orange: Adventurous
Gold: Responsible/Organized
Any thoughts on whether this is a legitimate personality typology or is it far too simplistic and general to be taken seriously?
