What the different paints have in common is that they are applied in a thin layer and form a matt paint film. As a result, different historical names have started to be used interchangeably for the paint that everyone, for example at school, grows up with: in Dutch plakkaatverf, in German Temperafarbe (with the addition of the darkened ""designer"" as a quality indication), in Spanish colores tempera and in French Gouache. Gouache is the best-known designation internationally, sounding a bit fancier than poster paint and therefore preferred by artists.
