Clear/ No color: denotes the parting face of the split pattern

Yellow: the seats for loose core print painted yellow.

Yellow strip on Red: indicates the seats for loose pieces.

Red strips on yellow background: for supports/ stop-offs

Black: the surface must be left as in the casting. This surface does not need a finishing operation.

Red: the surface which painted red required to be machined
