The easiest and fastest method for a non-designer with access to Photoshop would be like this:
With a little more effort, you could make a much better finish.
There are many other methods to achieve this, as it's a very simple task with the right tools.
There are lots of methods to achieve what you want in Photoshop.
You can use a non-destructive method such as a layered Gradient Map.
Take note that the signature isn't cut out from its background. If you want a transparent background, simply flatten all layers and use the Magic Wand. The selection will be more accurate with lesser tolerance adjustments since the image now has a higher contrast.
Let me outline another approach I find useful especially in the context of a signature for letters or PDF documents.
We can quite easily create a vector graphic from a scanned original signature. This can be done with a variety of applications. Here is how I made it using Inkscape.
We can then further refine the resulting colours, or apply variable transparency levels to the objects created if we need better results.
A vectorized signature has the advantage that it can be smoothly resized to any size, can be differently coloured with no effort, and it can be embedded in a variety of documents as a rather slim vector graphics.
