I want to grab one of the colors from a gradient, and turn it into a solid color swatch.

Update

Just to be precise, I want to get the color of one of the 'nodes' in the gradient. So if a a gradient goes from red to blue, I might want to grab the exact color blue from the blue node – i'm not wanting to grab any of the inbetween colors.
