You mean the fact that Lhikan isn’t canonically yellow? Maybe I just heard that wrong.
I’m curious as to whether people think the contests should have the power to canonise new native colours. Like, I’d really be interested to see a green and white or green and grey Nidhiki, because white and grey seem like Air colours to me. Hahli’s Toa forms did give us white and lime green Toa of Water, so it’d be cool to see some experimentation (if Greg says he isn’t just shades of green, that is).
Bruh what are you talking about. Metallic colors are a natural occurance in Bionicle even in characters that weren’t transformed through some weird mumbo-jumbo shenanigans. Giving Nidhiki some silver bits wouldn’t “canonise a new native color”, silver is treated almost like a neutral color similar to black and grey due to the overabundance of it.
Besides, it’s not like metallic colors indicate anything special. Zaktan and Reidak have gold torsos after all.
Depends on the Toa.
Nidhiki/Zaria: we already know their colors. At best, maybe some highlights
Orde/Varian: Since we don’t have an official appearance of a Toa of Psionics, I feel like the first one should be strict blue/gold. Once we have a baseline, then maybe the second contest can deviate. Though, since Psionics is a two-tone element, I feel we shouldn’t go too crazy, but some added color wouldn’t hurt
Chiara: we already have a Toa of Lightning, so I guess some deviation is fine. Since Lightning is a two-tone element, I feel we shouldn’t go too crazy, but I’ve seen people give her silver to match the Volitak and I think that’s fine (but I won’t vote for it)
Tuyet: go nuts, so long as it’s primarily blue.
By the way, there is a precedent for this: look at some of the Helryx models. They had white, silver, green, even orange.
I was talking about nonmetallic colours there. But yeah, silver is pretty much a staple colour whatever element you’re from. The canon rules are pretty loose on this so I don’t see why Nidhiki can’t have silver unless we take Greg’s quotes to mean he’s literally just green.
I imagine people will make the argument “but they’re Skakdi, not Toa”, but it’s a valid point.
I think the ‘can a Toa of element x have colour y’ discussion can be solved by deciding whether the colour is part of their body or their armour. Tahu Nuva only has silver because it’s his armour, rather than his body. Meanwhile Toa of Iron are the only Toa that can have an actual gunmetal body. And that makes sense - why can’t a Toa of Air stick some gold armour on himself if he wants to?
I bet there’s a Greg quote or obscure bit of lore that contradicts this. But at least I tried.
Oh wait Hewkii Inika is gunmetal. Hazash awaaaaaaay
Matoran jaller has yellow, but I think Toa Lhikan was not.
(the reason is,
The reason is that, as far as I know, Greg has never denied when Lhikan’s armor was described as “gold”, nor has he ever corrected it by saying “No, it’s Yellow”, in this question or any other statement.
I am very sorry again, but I am not that extreme of a supporter.
What I mean is that each Element colors proposed by Greg are just “basic”, and Nuparu-Orange, Onepu-Purple, etc. are just “colorings that deviate a little from the basics” or “examples of such things”.
(However, I’m very interested in colors such as white, which can be quite effective at impressing MOCs if used well, as long as they don’t become additional canonrise to Elemental colors)
In fact, Krakua has Gunmetal, the “Magunetism-color” on his chest, and Hahli looks like Toa of Plantlife.
However, she has never been mistaken for a ToP by the characters in the story, and is somehow “understood” by them.
As Greg and the design team indicated in their text and appearance, "The shape of Kanohi is only a sign, and there are variations.
So I just think that Elemental color also has a “Regular”, and that occasionally there are those who “deviate” from it.
Oh, in that case yeah, I agree, though I wouldn’t totally discourage the usage of some unique accent colors. Maybe not in Nidhiki, but some other characters. After all, Hahli Inika did have white despite it not being the color of her element, same with the lime green in her Mahri form, or one of my favourites (I know it’s G2 so the rule doesn’t apply here, but still) - Uniter Tahu’s dark azure.
Let me point out that all of these were allowed:
I think TTV’s stance (so far, anyway) is “variant colors are acceptable”.
Time to make me a pink Tuyet
(Honestly, I can’t guarantee that it will win, but my personal desire is to see a “Pink & Blue Tuyet that you built seriously cool”.
Hopefully, she could looks a ominous and beautiful… 
)
Pink and blue isn’t a bad combo. My Naho has some pink. It works together kinda well for a Toa of Water. Could be seen as some coral like stuff
I’m waiting for someone to finally make a pink and sand green Toa of Water to represent coral
then I can die happy.
I did have that idea a while ago. Though I’ll leave that as an open invitation for someone else to try. I’ll only be entering the Varian and Marendar contests.
Though I’m wondering whether I should revisit an old project to expand the colour palette of each element. 
Speaking of colors, that brings up an interesting question: if we were to have a Johmak contest, what LEGO color should she be?
Her official color is Ebony, which is actually a very dark brown. Technically, it’s somewhere between Lego’s black and Dark Brown colors.
Greg’s at it again with the obscure colours 
I think either black or dark brown would do, though there are no G1 parts in dark brown so we might need a similar allowance as was done with Artakha.
Dark brown heck yeah
Let’s get wacky with these colors
Slight change of topic, and sorry, but I just can’t leave the opportunity unseized that this also exactly describes the canon contests as a whole from my and some others’ positions.
Only instead of merely loud music it’s rather comparable to the government repeatedly thrashing your home.
As to Tuyet’s colour scheme - I’m personally in favor of Metru blue and gunmetal here. Fits the character, works well with Metru blue and adds no crazy accent colours. Exploring the darker shades of the Water tribe could also be interesting.
It’s worth considering that he might’ve just meant black. Roodaka was also described as Ebony, after all. (Birth of a Dark Hunter)
I was wondering if Greg had said anything about the color of Lhikan, so I checked the Ask greg archive just now, and found this statement.
In this answer, Greg responds with “the reason for making the toy”, but at the same time admits the fact that Jaller-Hau is “yellow” and Lhikan-Hau is “golden”.
(In addition, we can now explain the reason for the discoloration as “Kanohi changes colors to suit the wearer” or “In this case, we were confused because the colors happened to be similar.”)
(I think if it was Kongu who wore the Lhikan-hau and it changed to green or turquoise, there would not have been so much confusion.)
Sorry for long text! 
As was Reidak iirc.
That is exactly what they do. Masks are grey when unworn. Specifically with this Hau we see it in the Ussanui set. Them not turning grey is a creative liberty taken by the movies.
