I've looked at both sister sites and I feel that the lay out is rather nice and pleasent, but the colors should atleast be swapped in the default given skin. On a personal note I'd associate green with RTSes and red with FPSes.
I've looked at the recently locked thread that had the "OMG PANDAS!" and "BUMP DIS THREAD FOR GREAT JUSTICE CUZ I CAN'T CONTRIB ANYTHING ELSE TO DIS THREAD". After looking at both Greenfox and Bluefox I could see RTSOwned using Greenfox as typically in most resource gathering RTSes and RTS games in general resources are green due to being the cash and money to supplying your attacking force. Thus leading to green being the prominant color in RTS games when it comes to association with colors to represent what is important what is not.
On FPSOwned the prominant color should be red. Red usually represents the rage faces that people throw on in online matches when they're owning or being owned by others. It also siginifies the enemy and the flashy sides of the screen when you're about to die or have been killed. Sometimes attacked. This is my lackluster input at the moment.
I might add more to my suggestion, but on a personal level the colors on the Owned sister sites, excluding PokerOwned, feel a bit mismatched and quickly choosen.
If you are going to contribute to my thread please contribute to it. Not post stuff that will anger KuRIoS and have him beat this thread into submission before locking it down.
Stickies, if you read them you will avoid the wrath of KuRIoS.
