To plot in a specific color, scroll down in :
so you can do something like
col = [1 0 0] %RGB triplet,
a= plot(1:5,1:5,'Color',col)
%or
b= plot(1:5,1:5,'Color','r') % r for red
%you can set both lines to a different color at once:
set([a b],'Color','b');
^just apply this logic to the 10 plots you are talking about.
