question: public int lightenColor ( int color , float factor ) { float r = Color . red ( color ) * factor ; float g = Color . green ( color ) * factor ; float b = Color . blue ( color ) * factor ; int ir = Math . min ( 255 , ( int ) r ) ; int ig = Math . min ( 255 , ( int ) g ) ; int ib = Math . min ( 255 , ( int ) b ) ; int ia = Color . alpha ( color ) ; return ( Color . argb ( ia , ir , ig , ib ) ) ; }
target:  Lighten the given color by the factor
