Fairly.
First, you must apply a small amount of black grain filler or you can use black wood stain. Then, sand the wood back to to achieve a pronounced grain effect. Smooth well.
Then, apply red wood stain on top and sand back several times. Once you've reached an even coverage of red and you've reached the depth of colour you'd like, you can use a few coats of Danish oil (sanding well between each coat) and then a couple coats of natural beeswax on top (buff well!) to achieve a nice satin finish.
Good luck! It's time consuming but easy, yeah.
