MS SSRS - Creating and copying custom palette

There are some preset palettes in Report Designer to use in charts. I did custom palettes because the variety of colours is not enough in preset palettes. I needed more than 10-13 different colours to the charts. I designed the custom palette using a colour pair system. In that system dark and light shade of same colour make one pair. That way bars in the chart or slices in the pie would be easier to recognize.
