The Select New Colour dialog appears when the user clicks the "Change" button in the Set Application Colours dialog. The Select New Colour dialog has a colour palette containing 279 (31 x 9) colours from which a colour may be selected. Users can also specify colours (that may not appear on the palette) by defining RGB or HSB values. The colour of the selected item on entry to this dialog is shown in the "Old colour" window. On entry to the dialog that colour will also appear in the "New colour" window. Thereafter, the "New colour" window will show any new colour selected by the user.
