The author examines the personality types’ body language, including posture, gaze, facial expressions, gestures, handshakes, and personal space. He claims that Red personalities tend to take up space, walk confidently, have firm handshakes, and use dominant gestures, such as pointing at people. Since they prioritize efficiency, Reds tend to move quickly.

Similarly, Yellows tend to be confident and move at a fast pace. They find it easy to make themselves at home in different places, and use open and relaxed gestures. This outgoing personality tends to smile often, maintain eye contact with others, and shows affection easily. Greens have more subtle body language. They tend to have friendly faces and are more calm and discreet in their movements than Yellows and Reds. This introverted type tends to speak softly and may struggle with public speaking. Lastly, Blues are much more distant and contained than the other types. While they can maintain eye contact, they tend to have “closed” body language, very limited and slow gestures, and a monotonous voice (Locations 1728, 1760). Blues may give or receive dramatic news without revealing their emotions at all; they also prefer to have a lot of personal space.
