The main colour scheme is yellow, with green as a secondary colour for the trucks in 4203 and 4204. The mining helmets are the only all-new piece in this theme, there are several new face and torso printings. All of the sets (except 30151) have dynamite and all (except 30152) have gold. The gold included in the sets is in bars, studs, and large crystals.
