Changing default 'g' color

I would like to change the default 'g' color for plots. It's too bright for presentations, so I would like set 'g' = [0 0.5 0] rather than [0 1 0] of the default. I do not want to change all the color though; the default colors for 'b' and 'r' are fine as is.

Is there a way to change the default of 'g' permanently or at the start of a function so that I do not have to manually enter "plot(... 'Color', [0 0.5 0]...)" every time? Ideally, I would just use "plot(t,x,'g')" to create a green colored line.

Thanks, Jack

I don't think it is a good idea to mess around with system defaults, especially if someone else is going to be using your machine. Maybe this is my cop-out way of saying that I don't know if this can even be done, but I'll propose a workaround anyway.

Say you plot some stuff:

figure(1)
plot(rand(10,2),'g')
figure(2)
plot(rand(10,6),'g')
hold on
plot(rand(10,5));

Then you could change the green stuff to your own version of green by just adding this line:

 set(findobj('color','g'),'Color',[0 0.5 0]);

See my demo on changing the default plot colors, attached in blue. You'd have to run this code each time as it is applied to a particular axes. I don't know if there is a way to have it changed for all axes that you might ever create now and in future runs of MATLAB.

The named colors such as 'g' have built-in values that there is no documented way of changing.

When no particular color is specified for a line, the ColorOrder axis property is followed. Image Analyst's demo shows how to change and experiment with it for a given axis. You can also set the root property DefaultColorOrder to specific RGB values. But note that these are distinct from the named colors.
