The invention relates to a method for the production of concrete blocks or concrete slabs of varying formats and sizes, whereby concrete is filled into molds for several blocks or slabs, the surface layer of which or the facing concrete layer of which has a base color and the surfaces, which have regions of difference colors, is puddled by means of vibration and/or compacting and subsequently hardened, whereby, before puddling, at least one portion of a pigmented and/or variously-pigmented and/or a color- and/or various color-containing finishing material is projected or thrown by means of at least one application device.
