Different or custom palettes are required for chart components in Report Designer, and for the standard measure pages. Attached is a complete list of the available palettes, with their RGB values in DEC and HEX.
In Report Designer, every chart component has a palette selector in the full editor and in the quick-edit panel on the left. Simply scroll to the desired palette.
New custom palettes can be requested, if you can provide the exact colour values. A palette has a minimum of three colours and a maximum of 16. Be aware that your palette will be available to other companies, though it will not be named in a way that identifies yours.
Note that in the newer Charts 2.0 / High Charts, the palettes cannot currently be applied and each colour can be set individually instead.
