Are you asking about the tops of the bar stools in that post? If you look at the third photo, which shows one top pretty clearly, you can see at the top, it is pretty dark, and then gets much lighter as you get closer to the near edge of the top - so it is not just one color. If you are asking for a stain to match that wood because there is a small scratch, your best bet is to buy a wood colored marker - markers - the link is to a set , here is another set with a slightly different colors https://www.homedepot.com/p/Rejuvenate-Wood-Furniture-and-Floor-Repair-Markers-RJ6WM/202676224 While it won't be an exact match, a marker that is slightly lighter usually does a good job hiding the scratch. If you are trying to stain bare wood ( either raw, or originally finished but stripped and sanded ) the type of wood you have will play a role - a stain applied to maple will look different than that same stain applied to pine, cherry or walnut. In that case, if there is a Woodcraft store near you, they usually have an extensive set of dyes and stains, you could take you phone and open up the facebook page in the store and let them help you out.

And one of the products they carry is General Finishes. Their colors in water based and oil are here. General Finish products are the best I've found to work with in producing quality.
