Are you saying all those are PvP only?
So speaks the world that can see in colour to the person who can only see in black and white.
At some point you realise this is pretty much pointless - with many they'll accept the concept of colour existing, but some won't and will scream at you about how irrelevant this concept of colours clashing or how having colour schemes is all wasted time when all that matters is bright and dark in ALL CAPS for years.
Then when you manage to assemble a package of reasoning that makes sense you'll be reported for badgering and trolling as even the forums are just more black and white action when everything is black and white.
Finally it becomes clear why they're quite so angry - everyone else clocked that there was no explaining red, green and blue to them long ago and stopped trying.
