One of the most underrated parts of Human Design is how your centers shape your brand voice. Not just what you say, but how you say it. The tone, the energy, the feeling people get from you. The way your content either lands... or gets lost in the scroll.
Each center “colours” our tone of voice and our brand message. The way we say things, and why we say them.
But defined centers are, of course, the ones whose energy is always there for us to pull from and express. The most important ones for your brand voice are the ones that connect to the Throat—Ajna, Identity, Emotional, Ego, Sacral and Spleen. But that’s not to say that the defined Head, or Root, aren’t visibly influencing how you express yourself.
For example:
💛 I have a defined Heart (Ego) center, so I naturally radiate confidence, and I help others feel more capable and powerful just by being in my energy. So when I speak or write, there's this undercurrent of “you’ve got this, and you know it” baked into everything. (Think: Samantha Jones’s unapologetic self-love energy)
💓 I also have a defined Emotional center, so my content is both empathetic and emotionally rich. I just naturally create connection before anything else. It’s not just what I say—it’s how I make people feel seen, validated, moved.
(Think: Glennon Doyle—raw, emotional, real)
🧠 And then there’s my defined Throat + Ajna, connected through the 23-43 Channel of Structuring. I love simplifying things that feel complex and giving people that click moment. I’m a translator between chaos and clarity. My content is always going to be practical, clear, and focused on making things make sense.
(Think: Simon Sinek’s or Tim Ferriss’s clarity and frameworks)
Now let’ me take you through all the centers so I can tell you what it’s tone is, and show you examples of how they sound in content.
I won’t mention the defined Throat cuz it has it’s 11 ‘voices’ via the 11 Gates, and we’ll talk about that another time, so stick around.
Head Center
Tone of voice: Expansive, questioning, imaginative. Speaks from curiosity, wonder, and a hunger to explore the "big questions."
Example:
Elizabeth Gilbert – exploration, spiritual wonder, questioning what society accepts as truth.
There is a wild, brilliant idea whispering inside you right now. It doesn’t care if you feel ready. It doesn’t care if you feel worthy. It just wants out.
The world doesn’t need another polished brand. It needs your wonder. Your aliveness. Your willingness to say, “I don’t know exactly where this leads, but I’m following it anyway.” That’s main character energy. That’s how you become unforgettable.
Ajna Center
Tone of voice: Structured, logical, insightful. Turns complex ideas into simple truths. Speaks from mental clarity and understanding.
Example:
Tim Ferriss – obsessed with systems, simplifies complex topics, shares opinions based in facts.
If you want to build a brand that turns heads, stop following the herd.
Test faster.
Fail smarter.
Double down on what actually moves the needle.
Main character energy means running experiments on your own life—and optimizing what works for you.
Be a case study in your own greatness.
G (Identity) Center
Tone of voice: Authentic, storytelling, vision & why driven. Speaks from self-expression, purpose, and a deep sense of identity.
Example:
RuPaul – self-love, identity as liberation, and purpose-driven branding through expression.
Your brand is not just what you sell, darling. It’s who you are.
When you fall head over heels in love with yourself—the quirks, the brilliance, the full damn package—you become a lighthouse. Stop dimming. Start beaming. The main character doesn't chase; she attracts.
Ego (Heart/Will) Center
Tone of voice: Bold, confident, self-assured. Speaks with conviction about worth, value, and personal power.
Example:
Samantha Jones (Sex & the City) – unapologetic, self-assured, bold in owning her desires and standards.
Darling, the moment you stop watering yourself down is the moment everything you want starts chasing you.
Big energy. Big ambition. Big results.
You weren’t born to fit in—you were born to own the damn spotlight.
Emotional Center
Tone of voice: Emotional, relatable, activating. Leads by feeling, creating depth and moving people through emotional truth.
Example:
Glennon Doyle — raw, tender, and deeply emotional, connecting through shared humanity. Tells the truth with tears and fire.
You will never feel fully "ready" to be the main character. You will feel terrified. Exposed. Tender. And still—you will rise.
Because deep down you know: You are not here to be background noise in your own life. You are here to be the thunder.
Spleen Center
Tone of voice: Intuitive, instinctive, present. Speaks with wisdom that's immediate, subtle, and deeply rooted in somatic intelligence + self-trust.
Example:
Dr. Gabor Maté – speaks softly but lands deeply—pure presence, clarity, and subtle power.
When you abandon your true self for approval, you wound the very soul you’re here to express.
But when you choose to be seen as you are—messy, brilliant, human—you become magnetic.
Real safety is found in reclaiming yourself, not in hiding.
Trust that your truth is louder than any algorithm.
Sacral Center
Tone of voice: Energetic, lively, grounded in lived experience. Shares from passion, gut knowing, and zest for creative expression.
Example:
Marie Forleo — vibrant, fun, and passionate energy that sparks people into action.
You were not put on this Earth to grind through life with a fake smile.
You’re here to thrive, to create, to dance with the stuff that makes your heart race and your soul sing.
The more you follow what feels good, the louder your brand becomes. THAT is main character energy, baby.
Root Center
Tone of voice: Driven, urgent, motivational. Brings pressure and momentum that moves people from dreaming to doing.
Example:
David Goggins – no-excuses, pressure cooker energy. Pushes past limitations with intensity.
Nobody’s coming to hand you the spotlight. You earn it. Every damn day. The moment you decide you’re tired of being overlooked is the moment you stop waiting for permission. Build the brand. Post the content. Take up the space.
Which of these centers do you have defined?
PLUS, here’s the beautiful thing about all this—different parts of you come alive depending on what you’re expressing.
Some days, I feel a surge of confidence and empowerment… that’s my Heart center lighting up. That’s when my content feels bold, magnetic, and energizing.
Other days, I’m deep in my Ajna and Throat, craving to explain something clearly, to make life easier for someone reading.
Different centers, different flavors, but all still me.
And you’ve probably felt it too. Depending on what story you’re telling, what message you’re sharing, different centers will step forward.
You might feel more emotional one day, more bold another, more driven or visionary or playful later on.
Your expression isn’t static. It’s alive. It moves through you, if you let it.

Okay but this is so validating?? As a Self-Projected Projector with just my G + Throat defined (hi, Channel of Inspiration 👋🏽), I’ve always felt like my voice comes from my identity. Like if it’s not anchored in my actual truth, it just... evaporates. Anyway, this made me feel really seen. And lowkey gave me permission to stop trying to manufacture clarity from centers I don’t even have defined.
I'm wondering how having a center unconsiously defined would express itself (all of mine are unconsious). Would it be more like undefined or is there a different nuance?
