How Red, Blue, Yellow, and Green personality types shape sales
Products
Sunday 28 September 2025Many entrepreneurs wear several hats when starting out. Not by choice, but out of necessity: there isn’t always enough budget to hire staff for every task. Sales often falls on their shoulders too, and that doesn’t come naturally to everyone. Yet, attracting new clients is crucial for success.
Understanding psychology can make a big difference in sales. Knowing what drives people and how they prefer to communicate helps in building trust and closing deals. One practical tool to support this is the 4-color personality test.
This 4 color test identifies four types: Red, Blue, Yellow, and Green. Each type has a unique way of communicating and making decisions. Learning to recognize these types—and knowing how to adapt your approach—can greatly improve your sales results.

The Role of the Online Sales Assessment
While understanding personality types helps in day-to-day client interactions, organizations often want a more structured way to measure sales potential. The online sales assessment from TestGroup is designed specifically for this purpose. It evaluates key sales competencies and identifies whether someone is more suited to a hunter, farmer, negotiator, or consultant role.
By combining the insights of The Bridge Personality with the results of the sales assessment, organizations gain a clear picture of both personality and role fit. This ensures that sales professionals are placed where they can deliver the most impact, while also giving managers practical tools to coach and develop their teams.
The 4-Color Personality Wheel and Sales Roles
In addition to the four main colors, you can explore the 4-Color Personality Wheel, which expands the model into 72 unique positions and eight distinct personality types. These include The Auditor, The Planner, The Visionary, The Entrepreneur, The Director, The Connector, The Mediator, and The Change Agent. Each of these types represents a blend of two colors and gives organizations a more detailed understanding of how personality preferences play out in practice. This deeper insight is especially valuable in sales, where matching personality to role can be decisive. By combining the 4-Color Personality Wheel with TestGroup’s sales assessment, companies can identify whether someone is more suited to a hunter, farmer, negotiator, or consultant role—and how their color profile supports success in that role.

What are the Red, Blue, Yellow, and Green personality types?
-
These are four color-coded personality types used in the 4-Color model. Each color represents a distinct set of preferences in how people communicate, make decisions, and relate to others. The model helps sales professionals recognise how to adapt their style.
-
How do these colors relate to sales success?
-
When a salesperson adjusts their communication style to match the personality type of the prospect, trust is built faster and the chances of closing increase. The article explains how to recognise each type (Red, Blue, Yellow, Green) and how to tailor your sales approach accordingly.
-
How do I identify which color someone is?
-
You can look for behavioural cues and communication style. For example:
- Reds are decisive, direct, action-oriented
- Blues are social, expressive, enthusiastic
- Yellows are warm, empathetic, caring
- Greens are analytical, cautious, fact-driven
Over time and with experience, you’ll become more proficient in spotting these cues.
-
Does this mean a salesperson must change who they are?
-
Not at all. The aim is not to become someone else, but to be aware of your own tendencies and flex your approach when needed. It’s about increasing your adaptability rather than losing authenticity.

What is the role of TestGroup’s online sales assessment in this model?
-
The online sales assessment complements the 4-Color personality insight by measuring sales competencies. It helps organisations determine whether someone is best suited for roles like hunter, farmer, negotiator, or consultant — combining personality with skill fit.
-
What do “hunter,” “farmer,” “negotiator,” and “consultant” mean?
-
- Hunter — focused on acquiring new business
- Farmer — focused on nurturing existing relationships
- Negotiator — adept at closing deals and handling objections
- Consultant — focused on understanding client needs and providing customized solutions
Each role tends to align differently with the color profiles.
-
What is the 4-Color Personality Wheel?
-
Beyond the main four colors, the 4 color wheel expands into 72 positions and 8 distinct personality subtypes (like The Planner, The Visionary, The Connector). These nuanced profiles combine two colors and give deeper insight into individual traits.
-
Can a person fit more than one color?
-
Yes. While someone may have a dominant color, most people exhibit traits from more than one color. This is where the extended 4-Color Wheel (and blended types) becomes useful.
-
How can organizations use these insights?
-
Organizations can use the combined insight from the 4-Color model and the sales assessment to:
- Place individuals in sales roles where they are most likely to succeed
- Tailor coaching and development efforts
- Improve team dynamics and communication strategies
- Increase overall sales effectiveness
