Three systems behind our feelings
Our emotions are shaped by three systems that evolved to keep us safe and well. They are often pictured as three colours: red for threat, blue for drive, and green for soothe. We need all three, and the aim is balance, not getting rid of any one of them.
The threat system (red)
This system protects you. It scans for danger and gives you feelings like fear, anxiety, and anger so you can react fast. It is powerful and quick because, long ago, missing a threat could be deadly. It is doing its job even when the danger is a worry or a harsh thought, not a real tiger.
The drive system (blue)
This system motivates you. It pushes you to want things, chase goals, and feel the buzz of achieving or winning. It gives energy and excitement and helps you get things done. On its own, though, it can leave you always reaching for the next thing and never quite satisfied.
The soothe system (green)
This system settles you. It brings feelings of calm, contentment, safeness, and connection with others. It is the feeling of resting when there is nothing to fear and nothing to chase. It is linked to kindness, warmth, and feeling cared for, and it helps the other two systems calm down.
When the systems get out of balance
Busy modern life and a habit of self-criticism tend to over-feed the threat and drive systems and starve the soothe system. We push hard, worry a lot, and rarely let ourselves rest or feel cared for. This is not a personal failing; it is a very common pattern. Compassion is the deliberate practice of building the soothe system back up so the three come into balance.

Small ways to feed the soothe system
The soothe system grows with practice. Warmth, kindness, slow breathing, and connection all help. Tick any you would like to try more often.

When to use The Three Emotion Systems
The Three Emotion Systems is a psychoeducation handout based on compassion-focused therapy (CFT). Consider this resource when shame or self-criticism is prominent, or when exploring how a client relates to distress and what a more compassionate response could involve.
It is designed to be read within therapy rather than as a standalone self-help tool: a therapist introduces it and discusses it with the client. You can preview the full handout above, then assign it for clients to read between sessions on any device or download it as a print-ready PDF. Where a short reflection is included, it offers space to respond to the reading.

The handout can be read on a phone, tablet or computer, or downloaded as a print-ready PDF. If it includes a reflection, answers entered on the Formulate platform are saved automatically and shared back with the therapist for review before the next session.
The CFT approach behind it
The Three Emotion Systems draws on compassion-focused therapy (CFT). CFT draws on a model of threat, drive and soothing systems to explore how clients respond to danger, pursue goals and experience safety or connection. Shame and self-criticism can be understood within these patterns. Building compassion involves noticing suffering and considering a caring, helpful response, including when kindness towards oneself feels unfamiliar or difficult.
It is intended as one part of a wider course of therapy rather than as advice or a diagnosis. The therapist can help decide how it fits the work and discuss what emerges.
