The renderer context you are accessing is the one that was used previously for map rendering - for next redraw it will be overwritten. In general you should not change anything in that context (it would be better if the context would not be exposed). The selection color is stored in QgsProject settings, the following snippet shows how the selection color is read: QgsProject* prj = QgsProject::instance(); int myRed = prj->readNumEntry( "Gui", "/SelectionColorRedPart", 255 ); int myGreen = prj->readNumEntry( "Gui", "/SelectionColorGreenPart", 255 ); int myBlue = prj->readNumEntry( "Gui", "/SelectionColorBluePart", 0 ); int myAlpha = prj->readNumEntry( "Gui", "/SelectionColorAlphaPart", 255 ); ... a similar code with "writeEntry" methods will change the selection color.
