Changing the color of kdensity line on top of histogram

[Bibek Sapkota]

I ran the following code to draw kdensity line on top of histogram. But it gives me a green color and I want to change it to blue. There must be easy way to do it. Help please.

hist mixlcorb_premium, kdensity bin(20) fraction fc(none) lc(black) lwidth(0.1) xtitle ("β of Premium", yoffset(-1)) legend(off) 
forval i=1/17{
      gr_edit .plotregion1.plot1.EditCustomStyle , j(`i') style(area(shadestyle(color(grey%30))))
}
