BTW, regerding your screnshot, I am bit tired having all these colors Qt::red, 
Qt::green, Qt::blue colors reminding me the MS DOS' CGA era. How about 
defining the sequence of colors(in kdelibs?), probably based on KDE 4's 
official palette. Such a sequence then can be used by default in KDE apps in 
charts?

KOffice's color styles could default to this color set for charts as well.

MSO 2000 cs MSO 2k7 colors:
