If you want to use a chart color scheme other than those offered in either the Legacy or Standard Chart color schemes, you can design and apply a custom chart scheme. A custom chart color scheme persists only to the chart to which it has been applied.
To create a custom color scheme:
Select the chart, and on the short cut menu, select Properties.
The Chart Properties dialog box is displayed.
On the General tab, select Color Scheme for Data Points...

You can change any of the seventeen colors displayed on the Choose Color Scheme dialog box.
