Defiant 5.0

So I had my '11 GT up on the lift the other day and I noticed something interesting. My sway bar linkages are blue. Now mind you, I don't know much about aftermarket sway bars and such. But I found it interesting that these would look so awesome for OE parts. The car was purchased preowned and it had already been equipped with 3.90's as well as beefier tires in the rear. Can anyone shed any light on this sway bar issue? I know that this question is probably stupid, but figured I'd ask anyway. Thanks!!!

The end links were most likely replaced with cushier urethane. Heavier sway bar as well. Feels and looks better.
