In art, the uniform design of works of art by an artist is called style. The style also describes the common characteristic features and properties of an era or the works of an artist.
There are a lot of “official” styles that you can stick to as an artist, but actually every artist develops his own personal style at some point; his handwriting, so to speak. With very specific characteristics of a style, you can, for example, recognize which artist a work comes from without having to look for the signature ... if it is an artist who has already made a name for himself with his style.
In the academic subject of art history, art styles are even explored in stylistics; this subject is so complex that it has been given its own course of study.
