Examples: Luffy’s Red Hawk, Sanji’s Diable Jambe post timeskip, Kin’emon cutting fire, Zoro igniting Ryuma, Vista’s flowers, McGuy’s electric swords – Elemental – the most advanced Armament Shade known so far, it allows you to create an element (which can be personalized) and use it in combat. Anybody could achieve this and Enhancement, but you can personalize Hardening (for example, Luffy having Haki tribal tattoo on his body in Gear Fourth, or swirly Haki outside Zoro’s swords) It’s been used multiple times in New World. It’s stronger than Enhancement and can be seen by people who posses Observation Haki. – Hardening – advanced form of Enhancement, it’s basically a black ‘armor’ surrounding your body or weapon. It was shown when Luffy punched Pacifista, Boo tried to attack Funk Brothers with his haki imbued axe and Zoro cutting Monet’s cheek. It can be imbued inside weapons or your body. – Enhancement – the invisible Haki that’s used, for example, by Kuja pirates. I will list possible Shades that were shown in the entire series: The stronger your will and dreams are, the stronger your Haki and Shades will be. Rayleigh said that some people specialize in one or two Colours of Haki, and I think that would mean not just using the Colour but also mastering the Shade.

Personalization of Colours would be known as Shades. Depending on those two, you can ‘personalize’ your Haki. I think Haki has a strong relation to character’s ambitions and dreams. But what is Haki? You can literally translate it as Ambition or Willpower. There are three Colours of Haki: Armament, Observation and Conqueror.
