The stain was custom mixed form "industrial tints and coatings": therefore no formula. The wood is Alder & some of the tints are in the caramel range.

If you need a color match for a particular brand of stain and wood species, I may be able to do that for you through my shop. It may however be more cost effective to have your painter do the match.
