Palette Repository Editor is a design-time dialog that allows you to create, configure, and manage user chart palettes in a TdxChartPaletteRepository component. Double-click the component on a form to invoke this dialog.

The Palettes pane on the left displays STANDARD and CUSTOM groups that contain predefined and user palettes, respectively. The adjacent Colors pane on the right side displays items in the selected palette. Each palette item consists of primary (Color) and secondary (Color2) colors. The Preview column demonstrates gradients between primary and secondary colors for all palette items.

You cannot manage the list of standard palettes or customize them.
