A process and equipment for producing multi-color concrete products, including architectural concrete blocks, concrete bricks, modular concrete products that are suitable for use in landscaping applications, such as retaining wall blocks, concrete pavers, and concrete slabs. The invention includes a hopper that is divided into separate sections, with each section intended to contain a differently colored concrete. Each hopper section includes a controllable discharge opening that permits precise control of the amount of each concrete color that is discharged from the hopper. The colored concrete is then transported to and dumped into a hopper of a concrete product production machine, where the concrete is blended into a multi-color concrete blend for use in producing the concrete products.
