The Noft phenotype is the manifestation of the Noft genotype in appearance, a set of seven parameters:

* Rear background.
* Body
* Headgear or hairstyle
* Eyes
* Accessory or pattern on the body
* Tint
* Size

Generations differ from each other in style and intention. Each generation is characterized by its own set of these elements.

Before a minting, the set of elements is uploaded to the constructor. The constructor selects one piece for each parameter. Which element is selected determines the byte code of the token. This results in tokens that are unique in their combination of components.

Also, a Custom Noft may appear in a generation. This is a Noft created in collaboration with the artist. It's not assembled from a set of elements but manually drawn from scratch, like a work of art.
