How can I fade an actor from green to red?

Basically I want to take an actor, and fade it from green to red. How would I do this?
Something to note is that my actor has a black border and I want to keep that.
I'm relatively new to Stencyl but I've looked around the different tutorials and done a lot of searching to no avail.
I was hoping it would come down to creating an actor exactly the same as this one, but red, and fading it in.

Thanks in advance to anyone that helps
