In OBIEE 10g the default Graph colors could be changed by configuring the pallete.cxml located at \OracleBI\web\app\res\s_blaf\chartsupport\palette.cxml file. In OBIEE 11g this can be configured by adding the series colors in<MW>\Oracle_BI1\bifoundation\web\msgdb\s_blafp\viewui\chart\dvt-graph-skin.xml or <MW>/Oracle_BI1/bifoundation/web/msgdb/s_FusionFX/viewui/chart/dvt-graph-skin.xml (in newer versions). Add lines after </SliceLabel> to specify the colors. Also make sure to take a back-up of the original file.

<!– decimalDigitUsed is false here so that non-percentage pie slices do not pick up this value
The DVTChartProcessor sets decimalDigitUsed to true if this is a percentage pie slice –>
