Station for the realization of coloring effects in a mix for the production of slabs, includes: —a working surface intended to accommodate a temporary support with a basic mix layer for the formation of a slab; —at least one dye dispensing device for emitting dyes towards the working surface so as to deposit them on the basic mix layer on the temporary support accommodated on the working surface; —movement means for the relative movement of the dispensing device above the working surface; —a control system connected to the movement means for controlling the displacement of the dispensing device so as to follow trajectories along which dyes are emitted towards the mix layer; —at least one tool movable with the movement means (18, 118) and intended to interact mechanically with areas of the mix layer for receipt of the dyes emitted by the dispensing device to achieve coloring effects in the mix.
