Reds are the most results-oriented of the four types. They want to know what needs to happen and want to make it happen quickly. They are decisive, direct, and comfortable with conflict: they see disagreement as a necessary part of getting to the right answer, not as something to be avoided. They can appear blunt, impatient, and domineering to other types, particularly Greens, who find their directness overwhelming. Communicating with a Red: be brief, be direct, and get to the point. Do not pad your message with social pleasantries or background context they did not ask for. Present options and outcomes, not feelings and process. If you have a problem with them, say it directly. They respect directness even when they disagree. What they cannot tolerate is indirectness, which they read as weakness or dishonesty. Yellows are the most enthusiastic and socially energetic of the four types. They love people, ideas, and new possibilities. They are often the most creative and persuasive people in a room. They can also be disorganised, easily distracted, and prone to overpromising because they are genuinely excited in the moment and genuinely forget the detail later. Communicating with a Yellow: start with the relationship, not the task. They need to feel the personal connection before they can focus on content. Make your message engaging and energetic: they switch off when things feel dry or procedural. If they have made a commitment they are failing to keep, the most effective approach is a direct conversation about how important it is to you, which activates their desire to support the people they care about.
