Colors in Matlab as a vriable

I want the user to choose a color from a menu for my object. Can someone please suggest what the best way to do it is?

My object is in another function which I have called in the main script. The menu is also inside the function.

Part of Function:

Auto.Farbe = menu ('Wählen Sie eine Autofarbe aus' ,'Red','Yellow','Green');

Main script:

Farbe = Auto.Farbe;

patch('Vertices',Auto.Ecken,'Faces',Auto.Karosseire_Flaechen,'FaceColor',Farbe)

Any leads will be highly appreciated.

Perhaps something like this:

M = [1,0,0;... red
     1,1,0;... yellow
     0,1,0]; % green
X = strcmpi(Auto.Farbe,{'red','yellow','green'});
Farbe = M(X,:);

Or else download this:

and use it something like this:

[~,Farbe] = colornames('CSS',Auto.Farbe)

Do you want your users to select colors by name or by appearance? If the latter use uisetcolor.
