Specifying the theme

Select Dashboard > Dashboard Properties > Theme.

On the Theme tab, you can specify a background color for a dashboard. You can pick a color from a palette, or specify a hexadecimal value.

To specify a background color:

Click the color sample.
A color picker is displayed.
Use the vertical slider to select the area of the color palette which contains the color you want.
Or, if you know the hexadecimal value of the color you want, specify it in the field at the top of the color picker. You do not need to specify the # symbol.
Select the color you require and click OK.
