Four colour modes are supported:

  1. AutoCAD Colour Index [8 bit]
  2. FLTK Colour Map [8 bit]
  3. FLTK Colour Wheel [24 bit] (Or the max supported system depth).
  4. X11 Colour Names Swatch [24 bit] (Or the max supported system depth).

AutoCAD Colour Index [8 bit]

png

When you click on a colour well, The AutoCAD Colour Index window appears. If the well colour exists in the ACI table, it’s index and RGB value are displayed; if the well colour is not found, the index field will show '-1' and the RGB filed will show '?, ?, ?'. The clicked colour is displayed in the large colour well at the bottom left, whilst the previous colour is shown adjacent. If you want to find a colour by its index value alone, click 'Show labels'.

The advantage of using ACI mode when exporting DXF is that Layers are given the same colour index value as the Isolate Group colour so that when you open the file in AutoCAD, the colours match.

FLTK Colour Map [8 bit]

256 colours provided by the FLTK library. The colours are unamed.

FLTK Colour Wheel [24 bit]

Full 24 bit colour wheel selector provided by the FLTK library. The colours are unamed.

X11 Colour Names Swatch [24 bit]

png

This swatch has 548 colours arranged by shades and tints. To select a colour, click on its button, not its name. The clicked colour is displayed in the large colour well at the bottom left along with its name, whilst the previous colour is shown adjacent. The advantage of using the X11 Colour Names Swatch is that Isolate groups will be assigned their own colour name, which also appears in the Log. For example:

UNIQUE EDGES
  Scale Factor = 10.000000000
         Units = Feet and Inches
TsQEIcosahedron 3V, Class I, Method 1
  Primal Lattice
   Total edges = 270
   Unique Edges = 3
    Edge    Quantity     Length
     E1     [60]         3.486154888 Feet or 41.833858656 Inches. Yellow
     E2     [90]         4.035482123 Feet or 48.425785476 Inches. PaleGoldenrod
     E3     [120]        4.124114893 Feet or 49.489378716 Inches. OrangeRed

    Total edges = 270

If you do not want the X11 colour name appended to the group, uncheck the item ‘Append X11 colour name’ in the Log’s “Output” menu. This menu is only active in this Colour Mode.

Generating Isolate Set Colours

Click ‘REGENERATE’ to generate a new set of Isolate colours, or fine tune the generated set by clicking on the colour wells. Each colour well corresponds to an Isolate group. There are 72 colour wells in total, which should be more than enough for most instances. When the number of Isolate groups exceeds 72, a random colour is generated for the group.

Each Colour Mode has its own set of Isolate colours; whenever the mode is changed, the corresponding set of colours are loaded from the prefs and the colour wells update to reflect the changed state. There is no need to click ‘REGENERATE’ every time you change the Colour Mode.

When the radio button ‘Use Isolate Set colors’ is on, the generated colours will be used for all Isolate sets (Faces, Struts, Hubs, etc). When the radio button ‘Use random colour each time’ is on, a new array of random colours is generated every time you click an element with the Isolate tool.
