What traits would you expect from a yellow personality type? In what ways should you adapt your behavior when working with a yellow-dominant person?
According to Thomas Erikson in Surrounded by Idiots, Yellow types have a charismatic personality and a bright outlook. Erikson says they see life as a smorgasbord of delights and are the first to try something new. Their driving forces in life are joy and laughter. Erikson writes that Hippocrates refers to this type as “sanguine,” which means “optimist.”
Here’s how to work with yellow-dominant people.
Working With a Yellow Personality Type
Set a cheerful tone. Yellow personalities are at their best when everyone around them is happy, so if you’re collaborating with them, Erikson recommends you create a cheerful environment. To signal that you’re comfortable and approachable, he says to use friendly body language, such as eye contact, smiling, and leaning forward.
(Shortform note: If your demeanor isn’t naturally cheerful, this body language can come across as disingenuous. A friendly greeting, a show of gratitude, or a compliment can all accomplish the same objective. For example, saying “good morning” to a colleague is a very simple—yet often overlooked—way to start the day on a positive note.)
Create structure. If you want to help a Yellow-dominant teammate, Erikson recommends you offer to create some structure by writing up the to-do lists or managing the schedule. They will appreciate someone else taking on this task, and you’ll probably be better at it, too.
(Shortform note: Be prepared for this personality type to deviate from the schedule you created, and resist the urge to respond in frustration. Sometimes, having any schedule at all is enough to keep a person on task, even if she constantly adjusts it.)
Hold their feet to the fire. Yellow types are great at coming up with ideas but aren’t as interested in the execution. Erikson says if you’re collaborating with them, it’s important to make sure they’re pulling their weight. Remember, they care deeply about how others feel, so if their procrastination frustrates you, tell them so.
(Shortform note: Contrary to popular belief, procrastinators like to have deadlines. It is the deadline itself that motivates a procrastinator to get to work, and without one they might never begin. If you’re collaborating with someone who routinely procrastinates, break the project into chunks and agree on deadlines for each task. Make it clear that these deadlines are important to you and give a casual reminder before each one.)
Persuading a Yellow Personality Type
Use flattery and personal connection. Erikson explains that Yellow personalities are the opposite of Reds in this way—where Red types balk at flattery, Yellows relish in it. Yellow-dominant people also care deeply about human connection, so they enjoy personal conversations. If you’re trying to persuade them, Erikson recommends you spend time chatting them up, find something you have in common, and throw in a genuine compliment for good measure.
(Shortform note: To help forge a personal connection, try researching the person’s interests ahead of time. One of the easiest ways you can do this is to spend a few minutes browsing their social media accounts before the meeting. Also, pay attention to personal items in her office. Are there sports memorabilia knick-knacks, or photos of her family at the beach? Identify something you can use as a conversation starter.)
Highlight the innovation. Yellow personalities love being the first to experience something, so Erikson says if you want to sell them something, you should point out the features that are new and exciting. For example, if you want to launch a new program in your office, point out that other offices haven’t yet tried it.
(Shortform note: While their ability to take risks is admirable, people who are chronically attracted to whatever is “new and shiny” can be taken advantage of. If you fall into this category, it’s important to resist your impulses, and take the time to ask yourself: Is this a real opportunity or simply an interesting distraction?)
Giving Feedback to a Yellow-Dominant Employee
Lead the conversation. Erikson reminds us that Yellow personalities tend to take over conversations, so be prepared to keep the exchange on track. He suggests you have a plan for how to open and close the conversation and know which points you want to make, with an example to go with each one. When they try to steer to a tangential topic, Erikson recommends being deliberate in refocusing the conversation.
