Love that you have control over the output!
I currently use Frank DeLoupe (an interestingly-named color picker) that sits in your menu bar: http://www.jumpzero.com/frank/
@FrankDenbow, one killer feature is that it copies the color right to your clipboard. And will show the value right as a hexstring. So if you need that, I recommend!
