How to plot a line of a certain color?

I have 7 lines on a single plot. I dont want to use the 'y' color code. How can I make my own color? I also want this line to have asterisks along it. So currently I have 'y*-' but again I dont want to use yellow

plot(x,y,'*','color','blue') plots in blue. plot(x,y,'*','color',[.5 .4 .7]) plots the RGB value [.5 .4 .7]. If you want lots of color names, you could use the rgb function to return the RGB values of just about any color. For example, plot(x,y,'*','color',rgb('blood red'))

Starting in R2019a, you can also specify colors using hexadecimal color codes such as #0076a8. For example, plot(x,y,'*','Color','#0076a8') plots asterisks using a custom shade of blue.

Of course Chad's answer is best . But I just thought I'd show people how to change the default color order that you get when you plot lines without specifying the color. Ever wonder how it plots blue first, then dark green, then red, then cyan, etc.? Ever want to change the default order so that it plots curves with the color order you want instead of the default color order, and without having to specify the color in every single call to plot()? If so, run the attached demo.

Starting in R2019b there is a new colororder command that you can use to change the colors of new and existing lines. This command takes RGB colors, color names, and hexadecimal color codes as input. For additional details about managing the colors and line styles in plots, see Control Colors, Line Styles, and Markers in Plots in the MATLAB documentation.
