st: changing line colors in Kaplan-Meier graphs

["Peggy Chrisman" <peggyc@u.washington.edu>]

Dear List,

I am trying to change the line colors in a KM graph so they are easier to 
differentiate, but I am doing something incorrectly. I have checked the 
FAQs, but as yet have not found the solution. If someone can point me to the 
solution I would be most appreciative.
Thanks, Peggy

Here is my code and error message:

sts graph, by(treatment) title(Kaplan-Meier Curves by Treatment) 
legend(order(1 "Untreated" 2 "Treated") lcolor(blue red))



 failure _d:  deathtrue
  analysis time _t:  survival_yr
(note:  named style blue red not found in class color, default attributes 
used
