Thomas Erikson's Surrounded by Idiots starts from a premise that is both obvious and uncomfortable: most of the frustration you feel with other people isn't because they're incompetent or difficult. It's because they process the world differently to you — and neither of you knows it.
The book is built on the DISC behavioral framework, which has been used in corporate training for decades. Erikson's contribution was stripping it down to four colors and writing about it in plain language. It sold millions of copies. That's not an accident. The framework works because it's specific enough to be useful but simple enough to actually remember.
The four colors are Red, Yellow, Green, and Blue. Erikson uses colors instead of the DISC letters (D, I, S, C) because colors stick. You don't forget what color someone is the way you forget whether they were an "I" or an "S."
Here's what each one actually means.
Red
Reds are driven by results. Not process, not consensus, not feelings — results. They make decisions quickly, often before others have finished weighing the options, and they find deliberation genuinely painful. To a Red, a slow decision is a bad decision.
They communicate directly. Sometimes too directly. Reds say what they mean and expect you to do the same. Subtext frustrates them. Emotional framing frustrates them more. If you need to deliver difficult news to a Red, give it to them straight — they'll respect you for it.
How others see them: decisive, confident, a bit intense. Sometimes a lot intense. Reds in full flight can steamroll people without realising it. They're not trying to dominate the room — they genuinely just want to get to the point and move on.
Their blind spot is people. Reds can underestimate how much their directness lands as aggression, especially to Green and Yellow types who read tone carefully. They can also miss important detail because they're already three steps ahead.
Yellow
Yellows are energised by people and possibility. They're the ones who walk into a room and immediately make it louder — not in an aggressive way, but in a let's have fun, let's connect, let's see what happens way. They're enthusiastic, optimistic, and genuinely love social contact.
They communicate expressively. They talk a lot, they use their hands, they go on tangents, and they circle back to the point eventually. Other types — particularly Blues — find this exhausting. Yellows find other types' terseness cold and unwelcoming.
How others see them: fun, charismatic, unpredictable. Yellows are often seen as the heart of a group. The problem is that they can be perceived as unreliable — and sometimes they are. They start things with enormous energy and don't always finish them.
Their blind spot is follow-through. Yellows love the excitement of a new idea more than the grind of executing it. They also tend to overestimate how much people want to hear from them. The constant talking that feels natural to a Yellow can feel like an interruption to everyone else.
Green
Greens are the steadiest people in the room. They value harmony, consistency, and relationships. They don't rush. They don't push. They show up reliably, do what they said they'd do, and expect others to do the same.
They communicate carefully. Greens listen well — genuinely well, not just-waiting-to-talk well. They think before they speak and prefer to have difficult conversations after they've had time to process. Conflict makes them uncomfortable, not because they're weak, but because they genuinely prioritise the relationship over being right.
How others see them: calm, dependable, a little hard to read. Greens don't wear their reactions on their face the way Yellows do. This can make them seem passive or disengaged when they're actually processing deeply.
Their blind spot is assertiveness. Greens will absorb a lot before they push back, which means small grievances accumulate into big ones. They also struggle with change — not because they can't adapt, but because they need time to adjust that Reds and Yellows rarely give them.
Blue
Blues are analytical. They want to understand how something works before they'll commit to it, and they want to do things correctly — not approximately correctly, correctly. Standards matter to them. Quality matters to them. Getting it right the first time matters to them.
They communicate precisely. Blues choose their words deliberately and expect the same from others. They're not cold — they're careful. Small talk feels like a waste to them until there's a foundation of trust, after which they can be surprisingly warm and dry.
How others see them: thorough, reliable, hard to please. Blues are the people who ask the question in the meeting that nobody else thought to ask — the one that reveals a flaw in the plan. This is useful. It's also, depending on the room, deeply unpopular.
Their blind spot is pace. Blues can get stuck in analysis when a decision needs to be made. They can also hold others to standards that most people can't or won't maintain, which creates friction — especially with Yellows, who find the perfectionism suffocating.
You're probably not just one color
Erikson's framework assigns you a primary color — and that primary tells you a lot. But one of the things the book acknowledges is that real people are blends. You might be predominantly Red but with enough Green to care deeply about the people you lead. Or predominantly Blue but with enough Yellow to actually enjoy presenting your findings.
The primary color sets the direction. The secondary shapes how it comes out.
That blend is where the real insight lives. A Red-Green is very different from a Red-Blue, even though both lead with the same dominant style. Same primary, completely different personality when you look at the full picture.
If Surrounded by Idiots made you curious about which color you are, the next step is finding out your actual breakdown — not just your primary, but the full percentage split across all four colors.
Huetype is built on the same DISC color framework Erikson uses. The quiz takes about five minutes, and the result gives you a percentage breakdown across all four colors: which is primary, which is secondary, and how the blend shapes the way you think, communicate, and handle conflict.
