Colours

Draw allows you to draw in up to 365 colours, numbered 1 to 365. By default all 365 colour numbers have colour definitions assigned to them:

Colour numbers 1 to 16 are assigned by default to:

The system maintains a dictionary of 61 colour names that can be used in place of colour numbers when specifying a colour or setting the value of a colour attribute. These names (which include the 16 given), their default colour numbers and RGB values are:

Note:
The actual RGB definitions of these colours have changed over time and this has led to duplication. White and Whitesmoke are both mapped to 255, 255, 255 and Orange, Brightorange and Gold are mapped to 255, 191, 0. The redundant colour names have been maintained for compatibility with previous versions of AVEVA Software. Refer to Color Mapping in DXF/DWG and DGN Export for information on how colours are handled in export.

White and Black will render on-screen so that they are visible: when the background colour is white, white is rendered as black, and vice-versa.

It is possible to change the definitions of colours 1-16 indexes using the COLOUR command. The syntax can take three forms, either specifying a predefined name from the system colour dictionary, or a percentage mixture, or an RGB definition. Typical examples are:

COLour 3 STEELBLUE

COLour 12 MIX RED 80 GREen 50 BLUe 50

COLour 14 RGB 0,141,188

Where a percentage mixture is specified all three values must be in the range 0-100. Where an RGB definition is given all three values must be in the range 0-255.

Note:
Only the definition of the colour index is changed. The definition of the colour name cannot be changed. For example, colour 5 (which is Green by default) can be changed to an RGB of 0 255 0, but setting an attribute to the name Green will always give the fixed colour 0 189 0.

Colour definitions can be queried thus:

Q COLour 12

Q COLour RGB 55

Colour attributes can be assigned values by number or name, thus:

LLCOLOUR 54

TXCOLOUR NAVYBLUE

When a colour attribute is queried, the name (for example, ‘orange’) is returned if available, otherwise the colour number is returned. If a number is specifically required (regardless of whether a name is available, a special colour-number pseudo-attribute can be used. The names of these are derived from the normal colour attributes, for example, LLCONU/MBER, TXCONU/MBER, FCONUM/BER.

It is possible to set all colour attributes on an element to the same value by the ALLCOLOURS command. As some Draw elements have many such attributes this is a convenient way of changing them to the same colour quickly. To set all the text colours and all the line colours separately the TEXTCOLOURS and LINECOLOURS commands can be used, thus, for example:

The list of colour attributes are listed. The special colour attribute values of DEFAULT, TEMPLATE, and UNCHANGED can also be specified but these are only valid in particular circumstances.
