Defining Colours

Catalogues and Specifications Reference Manual

Common Commands : Defining Colours


Keywords:	COLOUR ACTIVE CE VISIBLE AIDS
Description:	These commands allow colours to be defined so that the status of different types of item in the display may be distinguished by means of colour. The colours used have default settings, but these may be redefined. The colours may be assigned by using the COLOUR command to define the Red-Green-Blue mix for a colour number or to assign a predefined colour mix by name. PARAGON allows the use of 100 user-definable colours, plus some specific ones which are assigned to items which need to be readily distinguishable in the display.

Definitions:

•

The Active colour is used for the catalogue component being worked on (the significant element, e.g. ELBO, VALV). If the current element is a geometric primitive, the active colour is used for all primitives owned by the significant element except the current primitive.

•

The CE colour is used for the element currently being accessed (i.e. the element highlighted in the Members list). This may be either a primitive or a significant element.

•

The Visible colour is used for any element in the display other than those to which the active or CE colours apply.

•

The Active and Visible elements together constitute the Draw List.

The predefined colour mixes which you may specify by name are as follows:

Note:

When colours are mixed in their Red, Green and Blue constituents, the command line must contain values for all three constituents in the correct order. The numbers entered for the relative proportions of the basic colours must each be in the range 0-100, but they are not percentages of the overall colour and so do not need to add up to 100.
