@adult: XD How are ya? Long time no see. Feel so lonely with all these new users. Miss r-pattz and her friends as well. Also heartisalone, Tamara, blindbandit, train, springly, sonic and others..
It depends on who tu ask. I say that they are either blue o a silver-grey, but most people say that they are violet. I've had some people say green, too. I have no idea how any of that really works, though... I'm fairly perplexed por it myself..
