Main cultivation of One Piece world is Haki.

There are 3 types :

--------------------------

Observation Haki or Color of Observation Haki or Kenbunshoku Haki :

Kenbunshoku Haki is a form of Haki that allows the user to sense the presence of others, even if they are concealed from view or too far to see normally.

The user can also use this Haki to predict an opponent's moves shortly before they make them, thereby making the attack much easier to evade with enough skill.

If trained enough, users of advanced Kenbunshoku Haki (such as Katakuri and Luffy) can even see slightly into the future.

---------------------------

Color of Arms Haki or Armament Haki or Busoshoku Haki :

It is a form of Haki that allows the user to use their spirit to create, in essence, an invisible armor around themselves, providing potentially incredible offensive and defensive capabilities.Notably, this form of Haki can be used to injure Devil Fruit users that are otherwise immune to certain kinds of physical harm, mainly Logia users.

It is mainly Black in color , but sometime it maybe like luffy red haki in gear 4th or some different colors.But mainly they are in black color.

-----------------------------

Conqueror's Haki or Haoshoku Haki :

Haoshoku Haki is a rare form of Haki that cannot be attained through training. Only one in several million people have this ability.This type of Haki allows the user to exert their willpower over others.

It is said that whoever possesses this type of Haki has the qualities of a king.

Haoshoku Haki is considered an extremely dangerous threat and a highly valuable asset by powerful groups such as the Marine Admirals and the Yonko.
