It might be able to die Koverall, but that is not how I see it used. You can tint your dope, poly, your clear whatever, and bring up the color by layers. From base coats up. In the PC10 debate, the brown shift has to come from the varnish darkening in the Sun. Ever see the antique furniture that is all black? Old boat soup type of varnish darkening over the years. Musical instrument builders are pretty picky so I think primary staining of wood either by directions or slipping some in dope might get the right look, and I am thinking on the PC10, a lightly tinted coat might be the thing.
