How to change colors of lines in survival plots?

unknown

Hi,

Hope someone can assist me.

I need to change the colors used in survival plots from the default colors to my own preferences. Until now, I have been using the "Customize" option, but

     (a) this is tedious if i have many plots to change, and

     (b) it leaves the legend unchanged, which is annoying.

I do not see any way to change this in thr Preferences/platforms option.

Any ideas?

TIA...
