Colors
From any report you can access the color palette. The palette contains 64 colors which can be used as cell backgrounds, cell borders, font-colors etc.
See Formatting cells.
In some cases, a subset of sixteen colors from the default palette is automatically applied. For example, colors are applied to the data series of charts. If there are more than sixteen data series, the colors are reused. So, for example, if there are seventeen data series, the first and the seventeenth display the same color. The subset of colors comprises the 34th to 49th colors of the default palette.
You can drag colors to different positions in the palette and use a color picker to select and add colors from outside the User-defined Colors dialog. For example, to pick a color from another application.
You can change the colors in the palette to use in an individual report. To use an amended palette in other reports, you can export it to an .xml file and then import it into the reports.
To open the User-defined Colors dialog, go to Design Mode and select or press <Shift+Alt+F9>.
Style sheet-based reports use the colors specified in the style sheet. This is regardless of whether the style sheet uses the default palette or a customized palette. To reuse a customized palette in a new report or style sheet, you must export it from the report or style sheet in which it was created and then import it.
This procedure illustrates the relationship between the color palettes of style sheets and of the reports based on them:
