Hello everyone.
I wonder if possible, put a border color to a layer, modified in size, style (Vix FX-crop border).
Without having to use another layer underneath, a little bigger and the color I want for the border.

I tried Shutter color shuttered, but the edge occupies the entire space of the mixer.

What I do is have a background layer and another layer in the center with a colored border.

Thank you very much everybody.
