Defining RGB color in curve fitting

I want to customize the color of my plots and error bars. When I enter 'r' for example where the [R G B] values are, the color shows up perfectly fine. When replaced with the RGB value, the connecting curve is no longer present on the graph. What do I need to change to make the line re-appear?

Thanks

I don't see in the help file for fnplt that you can specify a color (though you must not be getting an error...)

You could try

f1 = fnplt(csp);
set(f1,'linecolor',[your values]);
