If French Polish affects the sound is somewhat a matter of opinion. Most, (or at least lots of us) will say yes. This is not to say that I haven't played great guitars which were lacquer finished, or would tell you to not get your guitar lacquer finished... There are some people like the renowned luthier Lester DeVoe who think that lacquer finishes don't have a negative affect on sound. I for one can't argue with Lester. Myself, I'll go with French polish any day though. Lots of times the orange (Conde and others) guitars you see are lacquer finished. One of our great luthiers can step up and correct me if I'm wrong, but I think it would be hard to replicate that Conde orange look with French polish. It seems that with French polish you would end up with a more natural or "burnt" orange than that bright Conde look, but I'm by no means an expert on the subject. As has been pointed out, you can get French polish which will come out with an orange, yellow, red or natural tint to it. It depends on the luthier's opinions on how many coats to use and so on. Also as has been pointed out, it also depends on the tint of the wood. My Castillo blanca is French polished, and its got a lot of red tinting in the finish. My Castillo negra has no color added to the French polish.

Machopicasso: from Chemistry Daily about nitrocellulose lacquer: "Drawback of these lacquers include the hazardous nature of the solvent, which is flammable, volatile and toxic, and the hazards of nitrocellulose, which is also used to make explosives." From Luthiers Mercantile: "The main drawback of lacquer thinner solvent based finishing is the hazardous nature of the evaporating solvent itself. Intermittent exposure to the lacquer thinner vapors is a potential health risk, so it is necessary to wear a vapor mask, and to avoid skin and eye contact as well, when working with lacquer or lacquer thinner. Strong ventilation of the spray mist while spraying, and of the curing instrument after spraying, is a must. While most guitar builders prepare for, or accept, the space, equipment and safety requirements needed to spray lacquer effectively, there is a small but growing number of amateurs and professionals working to eliminate hazardous and toxic materials from their homes and shops. For these builders solvent-based lacquer is problematic." also from Luthiers Mercantile "The advantages of using French polish as a guitar finish are related to both the finish and the process. The beauty of the wood under this finish is undisputed, and it is generally regarded as the best finish for tone. Even with these accolades for the finish, the actual process, French polishing, has benefits for the maker. It is very “organic”, very personal and tactile. The finisher can watch the surface closely as he works and can minutely adjust material and method as the finish slowly builds and improves through multiple polishing sessions. This direct connection to and control of the results will certainly appeal to many craftsman. There is no equipment required, the materials are few and inexpensive, and the finishing can be done in a very limited space. The vapor and material are not hazardous or toxic, no need for air ventilation or face mask. This finish can easily be repaired or refreshed at any time. Additionally, shellac is used as a sealer or initial wash coat under any finish."
