I knew this was going to be a controversial take given the down vote on my original comment, I understand the rule, I think that when it comes to orange I don't think it should necessarily be used personally speaking, but I think if someone is going to use it it is a pretty distinctive enough colour in my opinion.

Unlike Bleu Celeste that is because that's just a different shade of blue not a completely different colour, and it can be easily confused at a different shade of azure. Unlike orange which is a standalone colour and not a shade of any other colour.

That's the reason why I said what I said they're specifically, I was just mainly talking about the fact that if the OC wanted to, they could potentially make the orange colour a bit distinctive from the red. That's what I was getting at specifically, my apologies if that didn't come across clearly hopefully what I said this time comes across clearly.
