Colour patterns

Painted object with more than one colour can be specified by listing those colours in a semi-colon separated list. When this is done, a colour pattern tag must be used in addition to the colour tag.

Horizontal stripes horizontal Straight bands or stripes of differing colours painted horizontally. HorizontalStripe.png

Diagonal stripes diagonal Straight bands or stripes of differing colours painted diagonally. DiagonalStripe.png
