No, this is not about faking stuff. A little bit of clickbait. ^o^
I wanted to suggest you to show the exact number of players actually playing, since premium accounts can join and therefore increase the number of players in-game beyond the cap. This has an advantage: people doing the queue will see for how much the cap has been exceeded and they will have a rough but more accurate idea of the time it is going to take.
As an example, if it's not clear:
13.000 people is the maximum. 500 premium accounts log into the realm. Now, website shows 13.500. Obviously, this would not have any impact to the queue display.
And yes, keep the color at orange when it's above the cap.
EDIT: Please, my bad, I posted this in Realm Suggestions subforum instead of the Website one, move it.
