PowerBuilder now supports the use of the full set of Windows system colors in controls. You can also specify and use 16 custom colors.
To see all the predefined, custom, and system colors available, open an object for which you can set color properties and view the list of colors in a color dropdown listbox in the Properties view. For example, select the background of a window and look at the BackColor dropdown listbox in the General properties view.
To specify up to 16 custom colors, select Design>Custom Colors in the Database, DataWindow, Window, or User Object painter.
