Users should also be familiar with Archicad's own Lightworks rendering brick materials.
These aren't obvious.
Accessing the LightWorks Material archive by using the "Load Setting From Archive" button in the Lightworks Material Settings Dialog and selecting the "03 Architectural" option yields a number of parametric brick materials if you burrow down far enough like a library ferret would.
You'll note that these materials can be programmed for color and variability.
