I'm planning to add black grooves to some built-in cherry cabinets currently under construction. There will be ebony plugs at the (domino) joints and I want to add some grooves such as seen in the attached photo.

How are people creating such black grooves?
I was thinking to apply a few coats of garnet shellac on the cherry face frames to color and seal the surface, then route the grooves, then paint in ebony stain or paint.
What's your approach?
