Erikson's breakout book introduces his simple four-colour model of human behaviour, drawn from the DISC framework: red drivers, yellow talkers, green steady types and blue analysts. It explains why the same words land so differently with different people, and how to adjust your own approach so you are actually heard.

A sequel that adds a darker figure to the four colours: the manipulator who charms, drains and controls the people around them. Erikson describes how to spot such behaviour early and protect yourself without becoming cynical about everyone else.

Erikson turns the four-colour lens on the workplace, from the boss who drives you mad to the colleague who never pulls their weight. He shows how reading each person's style helps you get along, get heard and build a team that actually works together.

This time Erikson looks at how we react when things go wrong, and why each of the four colour types stumbles in its own way. It is a practical book about setting a real goal, planning honestly and getting back on your feet after a failure.

Erikson applies his colour model to narcissism and everyday toxic behaviour, whether it comes from a partner, a relative or a coworker. He offers calm, concrete ways to recognise it, set boundaries and keep your footing without losing yourself.
