Abstract The talk focuses on the changes in the techniques of Fine Arts, the impact of this process directly on the art and also about the problems which are faced by modern restorers in working with old works of art. E.g. in the middle of the XIX century, there was a transition from paints, which were based on mineral dyes, to paints, which were created on artificial dyes. Before that, as a rule, artists mixed their own paints, and with the advent of industrial production switched to using purchased ones. It is now becoming clear that much of the work of the Impressionists and all who came after, look a little different than they did 100 years ago. The dyes have discolored. This problem is common to all modernist art. Using a couple of works from the Museum's collection as examples, I will tell you how restorers are trying to deal with this process.
