Not again, please. I have already destroyed you several times and you keep insisting from time to time, no matter how much you repeat something, it will not become true.
The manga written by Oda (cannon) is in black and white and we have to analyze that one, the rest can only be specific references. And the CoA has been shown to be black, hence we have epithets like the Black Fists Zephyr or the Dark King. Likewise, we know that swords with CoA become Kokutos, or black swords.
At no time has there been any reference to the CoA having different types of color, or that it changes according to emotions, or anything. The same for the CoC and AdvCoC, in principle it should be black.
And coincidentally, the only cannon image, drawn by Oda in AdvCoC color, is black:
In the color manga, the Haki will depend on the color that looks coolest with the composition. And you yourself have shown that it should not be taken seriously when the same scene in the Vivre Card and the color manga are different. Any argument that is not based on something made by Oda is useless, so forget about the colors.
Now I will proceed to study the cannon material
This is the first attack where we know that there is AdvCoC since Luffy (Oda) tells us so.
- The first thing we notice is that the mallet does hit Luffy.
This is already proven to be false. At no point are we told that hits with AdvCoC don't touch. And apart from this there are several other examples. Precisely, it has been the AdvCoA that has defined us with the ability to hit without touching. So Zoro can't have AdvCoA because he hasn't shown to be able to hit without touching like you said.
Only when facing two attacks with Adv CoC, they will not touch. Since King has no CoC, let alone AdvCoC, it's normal for swords to clash.
- The second thing we can notice is that there is a new visual effect, the trails, that start from the weapon/imbued part in CoC. It is something that had never been shown, neither with CoA, nor with AdvCoA, nor with normal CoC.
If a new power and a new visual effect appear, it is logical to think that both are related.
Now let's study the evolution of Zoro with the CoC
This is the moment when Zoro awakens the CoC and coincidentally is when the contrails appear. They don't appear during the fight on the roof, they don't appear when Enma gets out of control (which is when the most CoA absorbs)...
That the trails appear in a panel that talks about CoC is more than enough proof that Zoro has AdvCoC. It's impossible to deny it, even Zoro haters don't, but you keep going over and over again.
Also Kaido says that Zoro has CoC just when he scars him. And we know because Oda confirmed it in an SBS that Oden's Toguen Totsuka (who left a scar which has been much hyped in Wano) also had AdvCoC. Knowing that both attacks are a direct comparison, both have to have AdvCoC and since both attacks lack the contrails, we can assume that both attacks had too low a degree of CoC, which makes sense because Zoro did it unconsciously.
I think the resemblance is more than reasonable. I think anyone with eyes can tell that in all three scenes she is using the same power.
These are all facts taken from material drawn by Oda, not color-based headcannon.
