Lemon, are you sure it wont change anything in nicknyan? that is why i made a new color pool!

@marcocorriero As long as they are the same colours within the pool, that is all it is, the same set of colours. Its like having two different brand of water, at the end of the day its still just water.

If formatting is the only issue then this looks good.

@commodore64x Can you line comment on what formatting you thinks needs to be changed? I didnt spot any...

[mayokek]

Second eyes are better, I can't spot any.

Needs an approved review from @OxLemonxO or @Wild1145.

This was already implemented by directly uploading it to the server (it is NOT on GitHub).

@Ivengix Thats not all that helpful...

This will need to be changed, assuming there is a merge of the 5.0.2 release as the forbidden tags system has changed. That's something I can change though once the PR goes in.
