There are some regional differences, but the techniques described here cover the traditional wall paintings across this area.
The wall paintings were executed on earthen plaster with the secco-technique.
The support was covered by a smoothened ground, generally in white.
Generally, this involved the geometric layout of the design with the help of snapped lines and/or rulers.
[10] Specific details were then achieved with small paint brushes employing a variety of colours: black, white, ochre or red.
