Murat Sinkil argued that the signature is a part of the painting and should not stand out on its own. In this context, his signatures show slight differences depending on the painting he made. His signatures as "M. Sinkil", "ms" or "MS" are in the color required by the painting. Sometimes it is rounder, sometimes longer, and sometimes it looks like it is under the paint. But it is always a part of the painting. In addition to many unsigned paintings, when looking carefully at a painting that seems to be unsigned, his signature can sometimes be noticed. After all, aren't the artist's paintings already his signature and biography?
