Requesting a Skype button

Pretty much as the title says, I want a nice Skype button to put in my signature/threads that isn't one that people use often like the ones on **********. I'd like the color of the button to be black. You can just link the image below and that'd be fine, thanks if anyone can help.

when you put it in your signature put it the brackets back again.
