The colour scheme dialog is invoked from the Edit menu.

It allows you to:

• Choose a predefined colour scheme.
• Choose coloured lines.
• Change the background colour.
• Permute the six base colours.
• Change the six base colours.
• Change the brightness of the central face.

The colours are computed from the six base colours and the brightness of the central face.

Permuting the Colours

Above the slide bars the six base colours are shown, with their labels.

The drop down lists of labels can be used to swap the labels around, hence changing the mapping of the colour scheme onto the diagram.

Changing a base colour

To change a base colour, first clock on that colour above the slide bars, and then use any of the six slide bars (Red, Green, Blue; Hue, Saturation and Brightness) to adjust the colour.

Changing the brightness

The brightness of the central face, and the overall brightness, is controlled by the lowermost scrollbar

Cancel Bug

The cancel button does not work; it merely dismisses the dialog box.
