Nov 17, 2018 at 1:52 comment added mittimithai The visual impact of varnishes on paintings does indeed seem to be due to surface roughness: researchgate.net/publication/… But I am pretty sure that "raw" paint layers are generally rougher than ones that are matte varnished, as varnishes generally darken. It is hard to believe that wet oil paint would be rougher (=> scatter more => look brighter) than dry oil paint.
