'Color' contains the colour that the element in the AutoCAD layer is to receive. The normal behaviour of the export function is that the elements themselves will have a colour, while the layer itself will have a white colour. This behaviour can be overruled by the environment variable %dxf_color_by_layer%, (see Tab Files). 'Color' has to be a numeric value or the character A. Colour references such as RED, GREEN, etc. are not allowed.

If the character A is used, elements in question preserve their colour number as used in CADMATIC Hull.

Note:     The colour numbers assignment is not necessarily always the same in CADMATIC Hull and in AutoCAD or other CAD programs. This means that although an element  has the same colour number in CADMATIC Hull and in AutoCAD if the character A is used, they can have different colours in both programs. For example centre lines are drawn with colour number 4 which is in the CADMATIC Hull standard white. The exported line in AutoCAD also has colour number 4 (when the character A is used) but in AutoCAD the default colour 4 is cyan.
