Change fill color and hist option

Dear all,
how can i change fill color with TH1F histogram plotted with “hist” option ?
This is necessary because sumw2 has been applied, but effect of SetFillColor
doesn’t appear. It appears only if fill color is black ?!

To reproduce:

TH1F h("h","h",10,-5,5)
h.Sumw2()
h.FillRandom("gaus",100)
h.SetFillColor(2)
h.Draw("hist")

Thanks,
Max

Solved, it was my fault with default settings.
