The book talks about 4 types of personalities : red, yellow, green and blue. These 4 can come in different combinations, ex. a red-yellow personality. The book also talks about how you can get along with each color and influence them.

4 Personality Types

Someone who is red is very task-oriented. They are abitious and like to always move forward. Fast=good. Some might find them bossy or not very good listeners.

Yellow people are optimistic and spontaneous. They like to be the center of attention. They can cheer anyone up with their good spirits. New=good. They are relationship-oriented. Bad listener.

Yellow

Green people are relationship-oriented. They are also people pleasers and fear conflict and confrontation. They are good listeners. Some might find them hypocrite, because they tend to talk behind you're back when they don't agree.

Green

Blue people work very detailed. They like to know everything before making a decision. They are task-oriented. They work relatively slow. Percise=good.

Blue

If you don't know which color you're dealing with : act green!

Green All The Way

It's a very interesting book, which I recommend reading. 

Do you ever think you’re the only one making any sense? Or tried to reason with your partner with disastrous results? Do long, rambling answers drive you crazy? Or does your colleague’s abrasive manner rub you the wrong way? You are not alone. After a disastrous meeting with a highly successful entrepreneur, who was genuinely convinced he was ‘surrounded by idiots’, communication expert and bestselling author, Thomas Erikson dedicated himself to understanding how people function and why we often struggle to connect with certain types of people. Surrounded by Idiots is an international phenomenon, selling over 1.5 million copies worldwide. It offers a simple, yet ground-breaking method for assessing the personalities of people we communicate with – in and out of the office – based on four personality types (Red, Blue, Green and Yellow), and provides insights into how we can adjust the way we speak and share information. Erikson will help you understand yourself better, hone communication and social skills, handle conflict with confidence, improve dynamics with your boss and team, and get the best out of the people you deal with and manage. He also shares simple tricks on body language, improving written communication, advice on when to back away or when to push on, and when to speak up or shut up. Packed with ‘aha!’ and ‘oh no!’ moments, Surrounded by Idiots will help you understand and communicate with those around you, even people you currently think are beyond all comprehension. And with a bit of luck you can also be confident that the idiot out there isn’t you!
