The Nine Human Design Centers, Defined and Open
The body graph has nine centers, four of them motors that bring energy, the Sacral, the Heart, the Solar Plexus and the Root. A center is defined when a channel connects it to another one, it's shown in color and it works in a consistent way. An open center is white, it takes in and amplifies the energy of the people around it, and that's where a person is most influenced and where they can learn the most.
Head
Defined The Head is defined, so inspiration and mental pressure come from within in a consistent way, with questions of its own to think about.
Open The Head is open, so it takes in and amplifies the questions and ideas around it. Not every question needs attention, and the wisdom is in knowing which ones are worth thinking about.
Ajna
Defined The Ajna is defined, so there's a consistent way of thinking and of making sense of things.
Open The Ajna is open, so it can think in many ways and see many points of view, without needing to pretend to be certain.
Throat
Defined The Throat is defined, so expressing and acting happen in a consistent way, with a voice that people recognize.
Open The Throat is open, so the way of speaking and acting changes with the people around. There's no need to talk to be noticed, and speaking works best when the moment invites it.
G Center
Defined The G Center is defined, so there's a consistent sense of identity, of love and of direction in life.
Open The G Center is open, so a sense of identity and direction comes from the people and places around, and being in the right place matters, because it brings the right people.
Heart
Defined The Heart is defined, so there's consistent willpower and the ability to make and keep promises, as long as rest follows the effort.

Spleen
Defined The Spleen is defined, so there's a steady sense of well-being, an intuition that speaks in the moment and a strong immune system.
Open The Spleen is open, so it's sensitive to health and well-being and can feel how others feel in their bodies. It can hold on to what isn't good for it because letting go feels unsafe, and noticing that helps.
Sacral
Defined The Sacral is defined, so there's a renewable source of energy for life and work, for the things that get a true response.
Open The Sacral is open, so it takes in and amplifies the energy of the people around it, and it's hard to know when enough is enough. Resting before exhaustion helps.
Solar Plexus
Defined The Solar Plexus is defined, so feelings move in a wave, and things become clear once that wave settles.
Open The Solar Plexus is open, so it takes in and amplifies the feelings of the people around it. It can avoid hard truths to keep the peace, and in time it can come to understand emotions deeply.
Root
